The Engineered ring! CNC cut from 7075-T6 aluminum, this ring has modified shifter gates & special profiles to allow 8/9 speed chains to shift hassle free. The middle ring is cut from thicker 0.190 plate to prevent the chain from falling between the granny & middle ring. The outer & middle rings have stainless steel pins to further enhance shifting.

отличная износостойкая звезда. Но немного тяжеловата. Зато никаких закусов цепи за все время эксплуатации.

Rated 4 out of 5 by Anonymous Tough Chainring
I love these, I have done 1200KM this year on hard, rocky all mountain enduro events and all 3 chainrings operate like new. Beware though you need a special washer to fix the innner ring to the middle. The discription on CRC is not that clear.

Rated 2 out of 5 by Anonymous too soft
Bought these at the end of November '09. It's now middle of October '11 and they are shark toothed. Is it too much to expect the inner ring to last longer? Well I'm going to try another brand. Two stars as it looks well machined but I don't think it's tuff enuff
