Just 3 hours in and I love it

" After 3 hours of riding I think I'll never change for round chainring. I'm not faster but i can feel much comfortable riding and linear effort. "

Impressed

"Initially, reluctant. However, after month of riding I am very impressed with the power distribution and no knee pain. AB undoubtable got it nailed. You won't even know your are riding an OVAL after 15 minutes time."

I love how well they shifting

" I'm absolutely impressed how well they shift, which was my biggest fear."

Smooth ride and easy on the knees

" I’ll never go back to round and will order one for each of my bikes. Super smooth, eased my knee pain, and has helped my climbs ten fold"

Skeptical at first but a complete convert now

" I was quite skeptical until a friend of mine got AB oval rings. He was blown away with how good they were so I got some too and have to say I’m absolutely delighted."

Improved my ride

"I particularly notice the difference climbing. Just seems to be easier and I feel like I’m turning circles rather than ‘mashing’."

How to mount direct mount Cannondale oval chainring:

Remove crank from the bike. Open the lockring with "Cannondale Hollowgram Spider Removal Tool KT012". Remove original chainring/spider.Generously grease the waved interface of the crank arm, then place new spider chainring same way as original one. Apply small amount of medium strength Loctite on the lockring threads and tighten it with torque of about 47-54 Nm. 

You will need "Cannondale Hollowgram Spider Removal Tool KT012" or similar to open and close the lockring. 

Just like with all chainrings, the bolts holding our Cannondale Spidering Chainrings together should be regularly checked to ensure they are tight. Each of the five bolts should be tightened to around 5 Nm. 


Our longterm belief in oval and development of our design, has led absoluteBLACK to become the most commercially successful oval chainring product in the world. So keep in mind that not every oval chainring is equal to an absoluteBLACK.
