If you have an older or lower level Shimano crankset that is not advertised as compatible with our powermeters, there is a good chance that it is compatible with a different Shimano crank arm that we offer Ride Ready powermeters on. There are many crank arms/cranksets that are cross compatible with each other. They may not look the exact same, but it is a great option to get you riding with power.
Below is a list of non-powermeter compatible Shimano cranks with its closest compatible Shimano Ride Ready crank. Insider tip, for the older cranks (105 5800, Ultegra 6800, or Dura-Ace 9000), check our clearance powermeters. We are continually adding new stock as we receive fresh inventory.
To help with finding a crank arm in stock, you can use your crank finder.
You will just need to check clearance and purchase the correct length.
