AbsoluteBlack Klinge NW Shimano 12 speed OVAL - Sort - SHDMOVxxBK

Ovale klinger gør dit tråd mere glidende. Tro det (eller lad være), men en rund klinge overfører ikke kraften til dit baghjulet så glat som en Oval klinge. 32T oval klingen har mindste diameter i døde spot (svarende til 30T) og største i spidseffekt zone (svarende til 34T). Det betyder, at du vil performe bedre med en oval 32T klinge i forhold til en rund klinge.

Shimano 12 speed klinge kan KUN køre med Shinamos 12 speed kæde på grund af anden tykkelse på tænderne.

HOW TO MOUNT ABSOLUTEBLACK OVAL CHAINRING FOR XTR M9100:

Using Hollowtech II BB Removal Tool (like BBB BTL-116 ), carefully open the lockring that holds the chainring on the crank(normal threads). Once the lockring is removed, take off old chainring, re-grease the splines on the crank. Place new oval chainring with convex side to the crank. Chainring/crank has special splines that only fit one way. Close the lockring to 35-50Nm of force. Chainring is only compatible with XTR CN-M9100 chains. Using other chains may cause chain to drop very easily from the chainring due to thinner than usual teeth. 

It is ideal for 1x 11 & 12spd and Singlespeeds. 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.

Ovality of the chainring is in range of 10-14% (dependent on size) and feels perfectly round when riding. 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.
