SRAM's Red 22 X-Glide outer chainring is the replacement ring for the 11-speed Red 22 crankset, and it's what you want when your outer ring has enough shifts on it that front shifting has gone from crisp to hesitant. The rings are CNC-machined from 7075-T6 aluminum, which allows for precision control of each tooth shape, ramp, and shifting feature . That machining is where the X-Glide name comes from — the ramps and pickup pins are shaped to pull the chain up onto the big ring quickly, which is what makes the Red 22 front shift feel the way it does when everything is fresh.

Sizing runs 50T, 52T, and 53T. The 50T and 52T are 110mm BCD, designed to pair with the Red 22 compact and mid-compact crank arms and their matching 34T or 36T inner ring. The 53T is 130mm BCD, which is the standard road pattern for the Red 22 standard crank paired with a 39T inner ring. Match the BCD to your crank arm — you cannot run a 110 BCD outer ring on a 130 BCD crank or vice versa.

This ring is designed as part of an integrated system with the Yaw front derailleur and a corresponding SRAM 11-speed inner ring. Chainrings, chain, and front derailleur are designed as a single integrated system for optimized performance, with the Yaw front derailleur cage rotating to maintain a consistent angular relationship with the chain, eliminating the need for shifter trim . If you replace just the outer while the inner is worn, or mix in a non-SRAM ring, expect the front shift quality to drop off.... Read More
