" 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."

How to mount CX Oval chainring to Sram crank:
Take the crank off the bike. Unscrew these 3 torx t-25 bolts from the crank arm. Then remove the spider+chainring combo you currently have there. Clean the splines and put some grease on them. Position the chainring in place (note there is only one way to fit this Sram chainring so you don't have to worry how to do it). Close all 3 bolts to about 5-7Nm.
Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur. It also does not require chain tensioner when using in singlespeed application. Riding out of saddle on the uphill will become more pleasant. These chainrings also help you to recover after knee injuries as pedaling becomes smoother and less exhausting.
The most advanced, Patent Pending narrow/wide tooth profile currently produced, guarantee minimum 12 months of excellent chain retention capabilities! We mean it. Always use a new chain with a new chainring.
