Quarq RED AXS Aero Crankset

Single-ring drivetrain simplifies functionality - 48 and 50t variants have fully integrated power into a direct mount aero chainring - 36-46t variants have spider-based power - Chainrings can be easily changed without requiring recalibration of the power meter - 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 - SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control - Laser-etched chainring finish is more durable - DUB™ bottom bracket adds durability and simplicity - Non-aero chainrings can be installed with a single tool, making gearing changes a breeze
