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