Ovals helped me with my osteoarthritis in both knees

" The oval rings continue to impress me and have made a genuine difference to my riding particularly as suffer from osteoarthritis in both knees. There does not seem to be as much stress on my knees and they don't ache when I have completed my rides. I am super impressed!"

Just a few hours and I’m used to them

" I had my AB chainring installed last week and after few hours of pedaling, boom, it hit me. This chainring made a big difference. My knees didn’t hurt, I felt faster on flats and uphill. "

Smooth ride and easy on the knees

" I’ll never go back to round. Super smooth, eased my knee pain, and has helped my climbs on technical ascents ten fold."

Better power delivery

" Initially, reluctant. However, after riding my 29er I was 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."

Great looks and even better climbing performance

" Super pleased with the overall look and performance of the chainring. I can 100% say that it does improve my pedaling while climbing and getting through rough uphill stuff. Each pedal stroke is now more fluid and cadence is better on those longer climbs."

Don't know what bolts to use with 32T oval chainring with integrated threads?

They are standard bolts. You can use a granny ring bolts (from 64bcd chainring) or use the ones that connect middle and big ring from 3X crank. You can also buy them from us in Bolts tab. Pick "Long" ones. Other sizes like 34 and 36T use "short" bolts.

It is the most advanced oval chainring currently on the market.
