Overview
A mountain biker running a twelve-speed Eagle setup gets a cold forged aluminum chainring here, with a direct mount interface and a Boost offset. The longer, positive-rake tooth shape is made to work with the Eagle chain.
The reason to buy is better chain retention and lower wear and noise, as SRAM describes it, in a ring made for its Eagle system. The limit is its narrow compatibility, since the listing says it is for use with Eagle chain.
Who it's for
Riders on Eagle drivetrains who want to change gearing or replace a worn ring. Anyone with a different crank mounting standard or chain should not buy it.
Pros and cons
- Cold forged aluminum
- Direct mount design
- Chain retention tooth shape
- Eagle chain required
- Direct mount cranks only
- Single tooth count in this listing
Performance notes
The tooth profile is meant to hold the chain and reduce friction, noise and wear, according to SRAM. Ring size sets the gearing: a smaller ring gives easier climbing at the expense of top speed. It must match the crank mount and the chain.
