  • Mount the power meter to the cranks and tighten to factory specifications
  • Apply multi-purpose bicycle grease where necessary
  • Install chainrings on the power meter (if chainrings are ordered)

Please note – while we tighten everything to factory specs, it is still your responsibility to routinely check your power meter crankset to make sure all bolts and nuts remain securely fastened.


Chainrings: The power 110x4 BCD chainrings based on the version ordered. In many cases, you can use your existing chainrings assuming they use the same configuration as the power meter you order.
