Once the lockring is removed, take off old chainring,re-grease the splines on the crank. Place new oval chainring with convex sideto the crank. Chainring/crank has special splines that only fit one way. Closethe lockring to 35-50Nm of force. Chainring is only compatible with CN-M9100,M8100, M7100 & M6100 Shimano 12spd Hyperglide+ chains. Using other chainsmay cause chain to drop very easily from the chainring due to thinner thanusual teeth.


It is ideal for 1x 12spd. Oval (elliptical)chainring does not compromise the work of clutch mechanism in rearderailleur(video at the bottom). It also does not require chain tensioner whenusing in singlespeed application. Riding out of saddle on the uphill will becomemore pleasant.
