Season:2024

Brand:Sram

Code:CK1288

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. Sram's RED AXS power meter kit adds Quarq technology to the one-piece chainrings for the lightest, stiffest, and most accurate power package available. Combined with the most durable chainrings ever, it is an unbeatable combination.

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
