Know before you buy
No, this specific upgrade kit is designed exclusively for the Rival AXS Wide system. It is not compatible with standard Rival AXS cranksets due to the differences in spindle length and geometry.
No, this is a left-side-only power meter. It measures the power output from your left leg and doubles that value to provide an estimate of your total power output.
The SRAM DUB spindle interface is compatible with almost all major bottom bracket standards, including BSA, PressFit, and BB30, provided you use the correct SRAM DUB bottom bracket for your specific frame.
Yes, once installed, you should perform a zero-offset calibration through your head unit or the SRAM AXS app. It is also recommended to perform this calibration before each ride to ensure the most accurate data.
