SRAM XX1/X01 Shifting Barrel Adjuster Description: We demand a lot out of our components, hard shifts under load, knocked around on hard rides and consistently exposed to the elements. No wonder parts break. The shift adjusting barrel is no different, hanging out in the open where it's vulnerable to being broken off. Now the short version, this is a replacement barrel adjuster for SRAM shifters. Features: Fits 2002+ and Eagle SRAM shifters Adjusts cable tension for proper derailleur shifting tension Compatible with either left or right shifter 2-piece aluminum with plastic grip Includes: Bar Sleeve Spring Index Pawl
