If you wish to purchase an assembly service (CUSTOM) then a list of compatible cranks for this solution can be found HERE. If you wish to purchase a READY crankset then this can replace another Shimano crank. If you have a different crank consult a good bike service to check compatibility and possibly replacement of the bottom bracket.
In addition, remember that it is possible to fit a meter to your bike if:
- You have sufficient clearance between the crank and the frame (check here)
- Your rear brake (if it is a lower “aero” brake) does not interfere with the meter (check here)
- You have original Shimano sprockets
