Yes! The XX and X0 Transmission cranksets can be upgraded with a matching left arm DUB-PWR upgrade kit. This spindle-based power meter replaces the left crankarm and spindle assembly, allowing you to add live, accurate power meter readings to your head unit.
The XX SL crankset uses a direct-mount power meter which is compatible with our new threaded-mount style chainrings. These chainrings allow us to save weight without compromising reliability. This option can also be used with the XX, X0, and GX cranksets but is designed to complement the style and light weight of the XX SL Transmission system.
