This kit delivers fully integrated Quarq power measurement within SRAM’s one-piece chainring design, creating the lightest and stiffest power system in the RED series. The unified chainring structure increases durability and shifting precision, while the 13-tooth delta between ring sizes provides smoother cadence transitions during front shifts. The result is a highly accurate, climate-independent power system with class-leading stiffness, crisp shifting, and long service life.
Features
 • X-Range gearing for wider range and smoother progression
 • Power meter integrated directly into the chainring to reduce weight
 • Accuracy within +/-1.5% with no temperature drift
 • Measures left/right balance
 • Crisp, consistent front shifting
 • One-piece chainring structure for increased stiffness and durability
