One... and Only - Nothing Between Muscle And Measurement

Built hand-in-hand with the XX1 drivetrain for the highest performance and a sleek integrated look, the SRAM XX1 was designed for X-SYNC and compatible with XX1, X01 and X1.

Light weight with an LED indicator and replaceable CR2032 battery, each power meter is individually calibrated at the factory to eliminate temperature effects on power measurement. An accelerometer for cadence means there is no need to install a magnet, with an IPX7 waterproof rating (1 meter of submersion for 30 minutes).

SRAM XX1 was built with a dedicated 1X drivetrain philosophy- making it simpler, lighter and more durable than any other. No matter where you ride, no matter what you're up against:
