Features:
- 2-speed chainring setup
- X-Range™ gearing technology gives you more range and a smoother gear progression (in combination with the RED 12-speed cassette), so you are always in the right gear
- the Powermeter is fully integrated into the chainring design and therefore it just adds 36g
- power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride
- Power Balance measures left and right legs separately
- improved front shifting performance for crisp and accurate front shifts
- unique Direct Mount chainring design (not SRAM MTB DM compatible) results in a lighter weight, stiffer, more durable crankset
