My others bikes will be oval too.
Excellent product, well engineered, thank you!
As for the Oval ring vs round. I’ll never go back and will order one for each of my bikes. Super smooth, eased my knee pain, and has helped my climbs on technical ascents ten fold. Absolute Black for the win!
Really happy to be getting behind such a great brand that just gets how to be a successful business with an awesome product. 5*
I particularly notice the difference climbing. Just seems to be easier and I feel like I’m turning circles rather than ‘mashing’. The shifting is just as slick as the Shimano Ultegra 8000 too. Customer service is also top notch. Packaging is a thing of beauty too. You seem to have really thought the whole package through very well and deliver an amazing product. Thanks.
Prime example it this last weekend, club did a 2 day tour, 380km with 5000m of climbing (240 miles with 16500ft) over two days in rural Scotland and the drive chain was still running beautifully at the end, it has hardly picked up any dirt at all. In fact I’m away out again today with no need to re lube or clean, you find me a liquid lube that can do that.
in my haste I installed with some old locktight and ended up with one of the bolts dropping out on a ride. Got in touch with Stan, and he sorted me out with a replacement bolt. No questions asked (other than which bolt) I wish half the companies I deal with had an ounce of this level of customer service.
Will continue to speak very highly of absoluteBLACK.
I should mention my hesitation at first when I bought it and no-one around had it to share the experience - I was only concerned about its knee effect. After so many kms with it I can definitely vouch for the positive effect it has on pampering the knees - for example if I ride another bike with round chainring, I can feel a slight knee disconfort whereas with the oval it's never there. I should also mention, my adjustment was instant - there was no break in period or funny feeling at first, it was just something that felt natural.
I also love climbing and improved my ride with instant hubs etc but the oval played a major role into making climbing enjoyable. Very pleased with it! Thank you AB for fine tuning oval experience to the right specs!
I finally decided to order some Absolute Black GRAPHENlube, and after just 3 rides I know for a fact that I've found a winner. I have been absolutely blown away by this stuff (and the customer service from Absolute Black... just top notch).
Most wax lubes I've tried will be pretty quiet to start, but within 20 miles or so the wax all falls off for the most part and the drivetrain gets super noisy.
So far I've done 2 indoor Zwift rides and an outdoor 60 mile ride today with a few buddies. I REALLY noticed today just how smooth this GRAPHENlube is, and it's dead quiet. My buddy even told me after the ride today that he couldn't believe how quiet my chain was. My chain I'm currently using is a Ceramic Speed optimized Sram AXS chain, I didn't realize until cleaning the chain before putting on this lube that Ceramic Speed's "AXS" chain is only a Force chain.
So I just placed an order for the Absolute Black Sram Red AXS GRAPHENlube factory optimized chain.
This lube is seriously next level and I recommend it to absolutely anybody.
Can't wait to get this new chain now.
As near as I can tell without instruments, with the elliptical chainring more than half the time I'm one smaller cog on the cassette than I was on a circular chain ring, with the same cadence. Climbing out of the saddle clearly delivers more power to the back wheel, which is really useful when exploding over obstacles on the track.
It took 1 ride to acclimatise to the new chain ring. Now it feels entirely normal.
The elliptical chainring makes no difference on descents but descending on a MTB is about overcoming fear and not touching the brakes.
The Absolute Black oval chainring is the cheapest 'go faster' upgrade I've come across in 45 years of cycling. Good job. Well done.
Mechanically they are fantastic, shifting is as smooth and dependable as it was with stock dura ace rings , granted you make the proper FD and chain adjustments as needed. Looks are also excellent ( most important, right?)
I was pleasantly surprised that I did not feel much of a difference, definitely not negative or anything that would make you feel like you would have to get used to them vs round, but it is subtle and better/ smother feeling than round. even after getting rid of “placebo” effect I do notice climbs feel better with these rings. Most likely I will be putting these on my road bikes as well. Customer service was also excellent. So far very happy I decided to try these out.
The Ribbed silicone grips give me the perfect feel in the dry or the wet.
I prefer not using gloves and have never found my hands slipping off the grips, but always suck to them.
Tacky and comfortable with vibration damping making me a happy rider on gravel of steep techy descents.
I will definitely have these on every MTB I own!
Fast-forward a couple of months in self-quarantine and I found myself watching most of WorldWide Cylcery reviews and came upon "Oval vs Round." I decided to watch it and found myself intrigued! I hopped over to the absoluteBLACK website where I reviewed all the posted material. To say I was blown away would be a bit of an understatement and thought this might be the product I was looking for. So I took the leap and ordered a 32 tooth OVAL for my Sram with boost 148. When it arrived I immediately installed it and went directly to my go to trail head, hoped on my MTB and started my warm-up. The first minute or so I noticed the unusual feeling in my pedaling. This subsided before my warm-up was completed (I have not noticed it since). I started up (and I do mean up) the trail and found myself working more efficiently in at least one higher gear. When I hit the first tough section of up-hill with rough terrain I found (as promised) I had the power to get up and through it where I normally would struggle. Since this experience I have ridden several other trails and on the flats. I found the ring to live up to expectations and more! All in all you have made me a believer in the power of "OVAL"!
I only have two complaints. One, I purchased a chain guide just months before installing your ring. It has the height but the narrow guide causes rubbing in the top and bottom gears (sigh). Two, the product did not come with a sticker. I have stickers from several of my favorite MTB suppliers going back decades adorning my bike work stand and would have been proud to add absoluteBLACK to that group.
I do not notice a difference between the Absolute Black and a round chainring in terms of motion - but Absolute Black covers every stroke and every tooth...
Good Luck with your purchase - appears many of us are converts
This chainring is on a rigid 29 plus bike that I use for BikePacking the heaviest this bike has been is just over 70lbs - reduced knee fatigue was needed. Since getting the sub compact rings, I didn't even ride with the new round Sram chainring that came on the SX cranks, I took it off and threw it into the spares for eBay corner and mounted an oval. I rode Edinburgh Capital Trail over 3 days with this oval boost chainring - no chain drops, no pain, nothing. You need to buy all of your bikes oval chainrings, round is wrong.
I took the leap on my gravel bike to try out oval sub compact chainrings after switching from a double set up.
The weight of the gravel bike loaded with bivvy stuff is usually about 45 lbs so I needed a lower ratio without switching out my Ultegra cranks. Absolute Black came up with their sub compact chainrings which where on my bike before the week was up after finding them!
I struggle with ankle and knee issues and I needed anything that would help, Absolute black claimed to reduce the load put onto knees.
I was SUPER apprehensive and during the first ride, I was convinced, not through marketing, not through social media posts, through actually getting on them and trying them!
Since riding oval by Absolute black, I have been able to cycle further and longer. I took part in the BearBones 200 which I completed in 25 hours and 45 minutes moving time and just over 28 hours elapsed time with zero sleep. This was the icing on the cake. Oval chainrings are for everyone. You really really need to stop riding round. Once you try these, honestly, you will not go back.
No e-bike for me!
With over 600 miles on the setup I couldn't be more pleased. Setup with Ultegra 6800 works just fine. Highly recommend.
If you understand that cycling has a lot to do with efficiency and therefore performance gains you will be hard pressed not to be convinced that an oval is the way to go. I have personally experienced many of the benefits claimed, a much "rounder" pedal stroke, better power delivery and an ability to hold power values for longer efforts, riding a higher gear, climbing technical terrain with ease and overall just a much more enjoyable ride !!!
I have been so impressed with these rings that I purchased the 52/36T ovals for my road bike today. Very highly recommended. Thank you AbsoluteBlack for a great quality product, that performs the way it was intended to.
Installed with new chain and did a couple of test climbs. I didn't really feel a difference per se...oval to round, but my legs felt the difference. I seemed to float up the climbs, standing. I was also able to float up climbs seated in a bigger gear than normal and no fatigue in the legs.
As others have said, my pedal stroke seems much more efficient (and I thought it was already pretty efficient)
Great product, great customer service. A very happy customer! Thank you!
The two differences I felt was exactly what absoluteBlack says to expect with this sub-compact set up. The first is the climbs. Don’t kid yourselves, you still have to apply force on the pedal to get uphill but there’s a certain ease on those power strokes.
Cadence is smoother than you would expect. And despite what your friends might think as you pedal, no - you will not be riding like a pony on a merry-go-round.
My SWORKS Venge was set up with mid-compact 52-36 and DA 11-28. Just not enough gearing for for the big hills.
I switched to absoluteBlack oval chainrings in compact 50-34. The small ring varies in equivalent torque between 32 and 36 depending on the position of the pedals. It works very, very well on the climbs! It saves your legs in the weak part of the stroke and puts the effort into the strong part.
What I like best is that I can sustain higher wattages at higher cadence. On some of the flats I kept looking down at the Garmin thinking, "I can't sustain this..." but I was wrong. For the same heart beat level I was generating 200 to 220 watts versus 160-180 with the old setup.
Very highly recommended.
I also just tried "sub-compact" 46-30 on my Bontrager - but that is a bridge too far. Yes it's great going uphill, but it spins out at 110rpm around 30mph or so. So for my location with my power output compact oval seems to be the way to go.
I have no affiliation with absoluteBlack. I stumbled upon their website and liked the price point and the science behind the product. I would be curious to hear what other people have to say about oval chainrings, as well as cadence and gearing on the hills.
I find the entire pedal stroke much smoother, particularly uphill. I also find I can get out of the saddle for longer periods (I'm a big guy.)
The 36 tooth inner ring works well for me. I'm confident I can get my conditioning right for the 36 over a standard compact 34 and the smaller gap (50/36 vs 50/34) makes for a better shift pattern for me.
There are only two things I'd call for:
- working on the chainring shifting for eTap - it works but it can be a bit temperamental
- produce the big ring in a white option - dirt and grease never shows on the red ring. I'm sure you could achieve the same in white
just wanted to say what a terrific bit of kit these Oval chain sets are. I went for the 46-30 set which bolted straight onto my 105 cranks, and all went back on my bike with no issues. On the road, and on the hills especially, the drive is smooth and quiet. I believe that for a 55yr old rider, this set up has helped with my lack of power, and is smoother on my knees and legs.
Also, in the "champagne" colour they look the "AbsoluteBollocks" !!!!
One of the best add-on bits of kit i have bought. Highly recommended.
As an English cyclist living in the shadow of the Pyrénées, I was more than a little disappointed to find that I had calcification in the arteries in my heart last spring. Some surgery and a little convalescence followed and I was given the all clear to ride again, but ‘doucement’. Not easy in a region where all roads rise and fall.
I purchased a set of your sub compact rings, 48/32. Fitting was simple, adjusting was easy.
In use, they shift as smoothly as I want (I run UltegraDi2). They allow me to continue to ride without undue stress where perhaps I might not be able to otherwise. Thank you!
Knee pain (not debilitating, but annoying) went away. Feel like I don't pedal squares when tired. Front ring shifts seem to go smoother/quicker, as well. Having a 38 tooth 1x installed next week on the CX/Gravel bike (11 sp.). Color me impressed!
Super product, just do not understand why not everyone drives this.
I have had an ongoing back problem and thought these rings could ease the strain on my lower back. YES they did and they have me back to enjoying my cycling again. No scientific data just pain free enjoyment.
Great product - Many thanks
An awesome combo, great ratio and both being NW should eliminate any chain issues. Variance in chain tension with the oval is minimal and makes no impact, drive train is silent and performed flawlessly on my initial rides. Very happy
I just installed a 36 tooth chainring and it made such a huge difference, and I couldn't tell in the pedal stroke.
I am convinced and impressed.
As always the presentation/packaging of the products is top shelf.
Coupled with this has been the excellent advice I have been getting from the technical staff regarding cog and chain maintenance.
I am one happy repeat customer.
Summer '17 meant the 32 went back on, great. I love the "oval" feel. A month ago I fitted a new AbsBlack 28 Oval.
Wow, it's just amazing on climbs. I can even stand to pedal as it just seems so much smother and more grippy than last Winter's non oval 28.
Oval mis the way forward.
Will definitely be back!!
Norco Mtn Bike. I'm incredibly impressed with this product and here's why.
I'm a pure climber, that's ALL I DO!! I only ride uphill! I'm a 50 yr old
retired male who bikes up forest roads in the US to Forest Fire Lookouts.
The national forests of the Western US are full of these lookout towers. A typical ride is a 4000 ft climb in 8 miles via a gravel road. This is my
hobby and I gear my bikes to be pure climbing bikes.
Your oval chainring had the following benefits for me:
1. Less aerobic fatigue
2. Less leg fatigue during and less residual knee ache after.
3. Faster climbing times
4. Eliminated stops to 'catch my breath.' Less taking of breaks.
5. Allowed me to stop taking rest days between brutal climbs.
Installation was simple: Remove the crank (this also gives you an opportunity to inspect your bottom bracket and properly torque the crank after re-installing). I watched the installation video on Absoluteblack’s website. Note: I needed a T30 Torx, not T25, to remove the stock Shimano bolts holding the small chainring against the big chainring. I didn’t have to raise or lower my front derailleur, and I continued using the same chain (it was relatively new). No need to remove links.
My first ride was interesting. If you don’t think about it, you may not notice any difference in your ride. Focusing on my pedaling, I noted more “fluidity” in spinning the cranks. I’d agree with others that these chainrings do make you a better pedaler and, perhaps, a bit more conscious of when to shift or if you’ve shifted too soon. If I slow cadence just a bit or get a little bit ahead of myself pedaling faster in a low gear, I’ll get what I call the “clank”, the sound of your pawls in your freewheel engaging and taking-up just that little bit of chain slack. I think (and I could be wrong) this has something to do with turning over the crank from its most oval to least oval. Another reason to pedal with a smooth cadence. All said, while it could be the “placebo-effect” of me wanting to notice a difference, I think I do—even riding up hills seems just a bit easier and now can I say it: more controlled, more even with each downward push of the pedal making the bike climb more steadily. I liked the inner ring enough that I since have bought the outer ring. I can report the same feeling and results with it.
It’s worth mentioning that the outer ring is finished beautifully. Nice anodizing and the design in the ring makes the bike stand-out. It looks good on the bike.
I have no time having to get used to the Oval,rides great!!
I'm going to mount them on my other bikes i am a fan for sure!!
View the pics of my Koga Beach racer with Oval in the Gallery!!
By pure chance l read the oval rings could relieve knee pain. I was hopeful but sceptical. After 12 months of using the ring, l've never looked back. No pain at all. I did have a twinge after a couple of weeks and thought I'd found a short lived solution, but it was a one off. A life saver for me.
In terms of how the ring feels to use, l can't say l've ever noticed the ovalisation. Power delivery is definitely smoother, but from my perspective that's just and added bonus.
Just ordered another ring for a new bike.
Setup:Shimano 5800 105 50/34.
After a month of riding on your prem. oval chains rings I have nothing negative to say. I'm absolutely impressed how well they shift, which was my biggest fear. If your thinking of updating your 105 crank or ultegra crank don't, just slap on these chain rings and your good to go!
I just removed my AB Oval 32 SRAM direct ring as the cassette and the KMC X10SL Ti chain had eventually worn after 16 months of UK riding, quite some of that riding in mud and grit. That's pretty impressive. The drivetrain felt totally fine ’til last week, then some gears just began to skip at the back. The Oval ring was to worn for a new chain though. (unsurprisingly).
Next time I’ll rotate 3 chains as absoluteBLACK now recommend.
For the Winter I've put an older 28t non oval AB ring on there, as it had been in the spares box since July '15 when I fitted the 32. That 28 had gone through the foul conditions of Winter of 14/15 and is still going strong (it was packed away with it's original chain and cassette, I’m pleased to say).
I'd kinda expected the 28 to be a touch easier to climb with which would be useful for the mud that is here now, but, I feel it's no easier than the 32, and the 32 oval was so much "smoother". Smoother in both spinning and when climbing out of the saddle.
I'll back on a new 32 oval as soon as I can put some wear on that 28 for sure.
Thanks absoluteBLACK, great quality gear in a world of built in obsolescence. Recommended 100% for design quality and build quality.
Thanks guys for great, high quality products!
Packaging, finish and speed of delivery were great again, and the price is entirely reasonable too. I have binned all my other (el cheapo) cogs which have lost a chain on two occasions - this has never happened with my AB cog, maybe it's the fact that the cogs are NW, maybe something else...? The extra width also means no perceptible damage to the freewheel body.
The oval chain ring does change the tension a wee bit on an SS as it goes around, but with a bit of persistence you can find the right spot.
Thank you for providing such a quality, innovative product!!!
Shifting feels a bit quicker than on my round Sram rings.
Be sure to put the small ring on correctly!
Bottom line: better climbing and I feel faster on the flats now that I am used to the big ring.
I'm glad absoluteBLACK found a way to make an oval 30t in the 104bcd!
I expected to feel some difference, but I honestly couldn't have dreamed it would have made that much difference! Wow! It's true that it's difficult to explain the sensation. You don't realize what a dead spot there is at the 5-7 o'clock position of your pedal stroke until it's not there anymore.
I can't express what a difference it the oval ring makes in steady climbs, but also in increased power for punchy climbs or to get up and over an obstacle.
WOW! I have been riding mtb' for 25yrs & you guys have solved a problem that I didn't really think needed solving. I tried the ring out today for the first time at Afan Argoed on The Blade, it is really amazing how the oval ring smoothed out the torque curve when climbing, no loss of traction due to over torque, no disproportionate effort on the down stroke, no pedalling squares, no stalling, really amazing.
The other revelation was when pedalling through whoopy sections there was just a steady cadence, no bottom out bump, no spin out on the down slope & no over torque on the up slope.
I am a convert, the oval ring is an amazing piece of kit for the 1 x 11 drive train, I will fit one to my single speed, I'm sure there will be a marked improvement in pedalling efficiency here.
Thanks for your hard work & development of this product
The machining is beautifullly done and sits on the dura ace seating lugs just like the original making for a very easy diy. Having a red decal saying "This side out" would save a few minutes.
The climb output as a result of clever manipulation of the biomechanics of a pedal stroke is sublime! I can get "over" the top of the gear I am in and I climb better for it
SMALLEST TRACTION RING AVAILABLE FOR THE POWER2MAX meter. Might fit on other 104bcd power meters.
The Chain ring is very well made and finished, and fitted onto my existing XT HT2 Crank with no problems. I just used the existing crank bolts and tightened to the correct torque, I did use a spot of 'Locktite' on the treads as well.
On the first ride I did notice a slight 'pulsing' at first but I soon forgot about it. The pedal stroke just felt smoother and I was able to climb better as the power delivery was constant.
Whether is was psychological or not but I seemed to be able to push a higher gear on short steep climbs.
I don't think I'll be going back to a round 'ring anytime soon.
Top product - well recommended.

Nice step up in power and the wide/narrow profile has made the timing chain feel smoother (and needs less tension to keep it on). Great product and you should think about advertising for tandem applications.
After 3 days riding and nearly 15000ft of climbing my legs felt fresh with no signs of fatigue. Believe the hype people.
I emailed the guys for advice on what size to buy and received a reply within two hours. After delivery I fitted the ring (quality is superb by the way) and after two rides I am very impressed. After ten minutes I stopped noticing that it was oval and I have never dropped the chain. With regard to the effect on my knees, it has been very noticeable. I seem to be able to push hard up climbs but nearly all the pressure through my knees seems to have gone. My knees definitely feel better after a ride. Also in some sections I seem to be pushing one or sometimes two gears harder. I was going to get rid of my SRAM 1x11 and change over to 2x11 Shimano XT (at a cost of about £350) but so far I'm happy to stick with the current set up. Next purchase is an inner oval ring for my road bike.
For me so far the futures bright, the futures oval.
I raced XC, cat 1, ages 29-44. 15th place, stoked! Would've placed 34th in pro:). Pass on the good news, you guys have a ring like no other, I'll be spinning Absolute Black from here out.
It only took half an hour for our legs to settle in, and after that each new ride it felt like normal.....until I got back on a bike of the same model. with normal chainrings.. Needless to say I'm back on the Absolute Black rings again.
Thanks guys for providing a product that delivers on its promise.
If you want a little edge that will help you go a little faster and ride a little longer, look no further. I am completely satisfied with my purchase and I highly recommend it. Basically this is a chainring on steroids! And the look of this chainring is killer!!!!
Doug Lockhart, Vancouver Island, B.C.
I love the ring, and have talked three of my customers into ordering them as well. So far 100% satisfaction!
I recently road the Dirty Kanza 200, if you are not familiar, it is a 200 miles of gravel and minimum maintenance roads through the Flint Hills of Kansas, in one day. Very tough ride with over 10,000 feet of elevation gain! I am convinced that the ring helped me finish 207.21 miles.
In August, I am going to complete in the Maah Daah Hey 100 mountain bike race in North Dakota. 100 miles of mountain bike single track in one day, with almost 12,000 feet of elevation gain! I am confident that my Absolute Black oval ring will once again help me to the finish line.
Doesn't feel weird at all / if anything more natural flow for my legs.
I'm a 201cm tall guy / and this feels more ergonomic and natural for long legs...
*(riding 1x10 with 11/36 rear and 32 oval nw up front. Used to have round 32 in front chainring)
The oval chainring makes out of the saddle climbing easier and I can maintain a much higher seated climbing cadence.
In all that time the chain didn’t dropped a single time! I love the way the oval chainring provides traction in the mud and on steep climbs!
Great job done guys!

Great job done guys!
I fitted the AB oval Sram GXP chainring and new chain/cassette and went for my first ride today. I received it a while back, but didn't want to use it whilst we still had a lot of mud. The 28T (direct mount GXP, one of yours) I took off still has life in it after many months use in some awful mud - I'm pleased to say.
Well, I am entirely amazed by the smoothing of pedalling with the oval ring, I always believed the theory but had never tried it. There is an MBUK / Fabien Barel tuition DVD with a section on climbing, he stands and is just so smooth on very steep loose terrain. My smoothness today had that same feeling, stronger through the whole pedal stroke.
I'll never climb like Fabien but anything that makes standing climbing on a low traction surface more feasible is a great thing to have. Didn't feel any harder to turn than the 28 either.
In short, I am amazed. It was as good for my ego as having a new bike, less bob on my 171 travel Nicolai AM with the smoother stroke too.
Well gone for redesigning the Biopace concept and getting it right.
What's not to like? Faster riding with less cardiac and less musculoskeletal stress.
Married now with a loving Singlespeed racing wife, two little girls and one on the way I once again have wheels under me for at least 70 miles a week, all dirt. As my fitness built I wanted more performance out of my bike. I bought a stiff and light set of wheels and a bigger chainring for my 2x10 setup. I got fitter and faster over the last year and now it was time to really get my power to the ground.I changed things up to a bike with a 1x11 and a solid rear end.
Back in the day I used a Rotor Ring and felt petty good results on my Singlespeed. So of course this time around I was thinking of getting another one. As I began my search I found an add on Facebook for Absolute Black Oval chainrings. A lot had changed in the mountain biking industry in the 5 years I hadn't been around. So instead of just going with Rotor Ring I read reviews on ABO's and I just couldn't find a bad review. Of course some guys were installing them and taking them off because they decided they just felt wrong but they didn't take something into account. They were just pedaling wrong, quite squarely actually, just like the rest of us. They didn't give the rings a chance to smooth things out. No worries tho cause they will be back. All the other reviews were astounding!
These rings work. They are not a fad and when people really catch on and come to realize the many benefits of using one, the face of mountain bike racing is going to change. A racer or weekend athlete who is already strong with a round ring will start to think after a hard day on the bike, how much better could I have done on an ABO??? 1x11 is catching on to the every day rider, not just the racers. It could really get more people on these rings and as they made the transition to 1x11 they would most definitively get one then as well.
So those are my thoughts and testimony on the awesomeness of Absolute Black Oval chainrings. I really look forward to spreading the word.
I will be installing AbsoluteBLACK oval rings on all of my bikes.
A great note about the absoluteblack customer care: simply amazing. I've returned a previous order due to my fault on choosing the size and in few days I've got the full refound ...in few words...amazing
It won't be too long before we wonder why we ever had 30 gears and round chain rings!
Not many pictures on the web, but it is a deep blood red which is a great match for the kcnc anodised parts, theres no machine lines like you see on some pictures, very very smooth finish, almost liquid looking. Strong enough for what it needs to do without the excess. It doesn't seem much when your talking grams but compared to the standard chunk of drilled metal its feathery light.
No regrets at all.
Funny how round an oval chainring feels when you are pedaling.
Just beginning to use, the quality and strength will be reviewed later
if you have aches and pains in your knees get this , if you want to go faster up hill get this , if you want to have more energy to do more km's get this .
Bottom line they work for me in the sense of smoothness , and up hill felt less knee strain.
Climbing on oval is much better, you can feel it instantly!
I'm very sure about this as I swapped between oval and round cranks a few times to prove it to myself. Climbing on round chainring generates some kind of tension and fatigue on knee zone. On oval that tension disappears and it feels easier to climb both seated and standing!
On oval chainring the pedaling feels more "round", more natural.
Every MTB rider should try the oval chainring. It worths!
Thank you AB for this excellent product!
Where I ride: San Diego North and East County (lots of climbing, loose, rocky, sandy terrain. Almost always dry).
What I ride: Pivot Mach 429 Carbon, Pivot Mach 6 Carbon.
How often I ride: about 6 times a week, 80-100 miles per week
Style: XC / Trail
Crankset: NEXT SL w/ 30T Cinch chainring
As many have already pointed out you don't get much gain when your RPMs are higher, however, I do feel that even in this mode of riding, my pedal stroke feels smoother and it isn't has hard to feel like you are "pedaling in circles" even though you are using an elliptical chain ring.
Here is where you notice it:
1) Aggressive bursts - getting crank up to speed takes less energy. Powering over obstacles, etc.
2) Climbing - you realize you are in 1-2 gears higher than usual - shifting up to your "normal" gear for a given climb is almost frustratingly easy
3) When recovering - the oval motion facilitates recovery - hard to explain but it does
4) Your lower back doesn't hurt
5) Standing - less stress in lower back as well as more traction
I want to emphasize #4 - I think a lot of lower back issues (including periformis) come from pedaling too high a gear and trying to exert too much force near the top of the pedal stroke on circular rings. With the oval ring, I feel that I can exert the same force, but the transition from the 1:00 to the 3:30 position where the power zone starts enables me to avoid that dreaded lower back strain I sometimes feel and which causes me to have to drop my exertion down a few notches until I can lead it out, or sometimes it just doesn't go away at all. Many of the comments focus on the dead zone, and the back stroke, but the start of the forward stroke at around 1:00 (not to be confused with where we get maximum leverage) I believe is yet another advantage of this approach, as the elliptical ring provides a mechanical advantage when your knee has more flexion and where you are using muscles in the lower back and upper glutes to start the downstroke.
Another thing I noticed is this chain ring is quieter than the 30T RaceFace ring that came with the NEXT SL crank I use.
Does it screw with the RD? No. The RD doesn't move as the crank rotates.
Does it screw with shifting? No.
Was it easy to install? Yes. No additional adjustments to shifting. No noises, not chain drops, etc. I just put it on, and went on my way.
Will I keep it on the bike? Yes.
The chainring is ABSOLUTE (lly) amazing, work great, really smooth.
I had to wait a little bit, but`s ok, and when you got it in stock, it arrived at my house in the next day, super fast
Thank you to contribute for our happiness
Thanks a lot for doing great components
I start from the least important fact = it looks simple and great! Well done!
I have heard from some of my friends that the ovality you can feel in your legs while pedaling and that it needs some time to get use to it. I coudn't feel anything while the road was flat and not demanding. Once the road turned uphill I felt like I might indeed be pushing more smoothly. But I was not sure if it is not just my will or imagination. So I took it from road to forest trails. I have one small hill behind my homeground, where is a turrist trail up to the castle at the top. Its quite an uphill, short, but with rocks and roots, with some switchbacks and steep parts. I was shocked how smooth the pedaling was. The elimination of the dead zone is absolutely fantastic. I have never been able to keep such a cadency on this trail, bottom to the top. On similar uphills I can keep pushing heavier gears than before, with no higher power output, it seems.
Second day I took it to a quite hard uphill, where I used to use round 30*40 gear and was at the limits. This time oval 34x37-42, which is heavier and with better feeling.
Great job there, I plan to switch my second bike soon as well.
I log a lot of long miles, with lots of long climbs and I feel noticeably less fatigued. I feel like I always have that little extra left in reserve I can tap into to power up the final part of a long climb. I really believe that the shape of the chainring allows for a better "resting phase" in your pedal stroke, lessening fatigue. I have a pretty smooth pedal stroke to begin with, and the oval didn't "mess" with this in any way. The feeling is slightly different, but I seem to be more effective.
Standing climbing is a whole other kettle of fish with the oval. I feel like it requires so much less effort. Like it really affords me an opportunity to rest my legs. Just awesome.
Technical climbing is improved as the ability to maintain traction is increased, and punching and surging your way up rocky climbs is effective.
First ride and I was in the saddle a lot and actually felt even through the pedal revolution.
Didn't think I could improve my ride that much. If I had to use one word to describe the Oval Chainring it would be 'Efficient'
I mounted it up spun the cranks and thought to myself "this is going to be weird", but I jumped on the bike and it did not feel weird at all. In fact, it felt just the opposite. My pedal stroke felt more natural and the cranks felt easier to turn. What was great was that moving from a standard 30t, my low gear felt lower, and my high gear felt higher. It felt like my gear range expanded. Super happy, can't wait to log more miles. All my best
