10, 11 or 12spd chain for geared bike or 6-8 spd for SS. If used in 1x9 drivetrain - 10spd chain must be used to obtain the performance. (yes - 10spd chain will work great on 9spd cassette). Oval (elliptical) chainring does not compromise the work of clutch mechanism in rear derailleur(video at the bottom). 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. It is the most advanced oval chainring currently on the market.
