Sram Quarq Red AXS DUB single-chainring power meter crankset

Power management is a key performance factor. In the single-chainring version, this is a choice that can pay off in specific races. The axle format is DUB standard, and the sensor accuracy is 1.5% for optimal effort management. You can access data for the right and left legs, with an ANT+ and Bluetooth connection to pair with the SRAM AXS app and perform updates. There are two versions available: a standard model and one with an aero chainring in 50- and 48-tooth configurations.

Power transmission will be seamless thanks to the ultra-rigid DUB axle and the carbon crankset. Your bike computer will display all the information you need to manage your effort; the rest is up to you!
