XPOWER METER CRANKSET:Can I Only Purchase the Crank if I already have a Power Meter Spider?

XACDEY cranks are only compatible with the XCADEY 5-Bolt power meter.
If you are using an XCADEY 5-Bolt power meter, you can purchase an XCADEY crankset.
If you are using a different interface, please select a crank from another brand according to the interface (refer to the compatibility list).

Note: Carbon cranks are only compatible with the new interface XCADEY 5-Bolt power meter; old interfaces need to be cut and modified to the new interface.
