Is my bike compatible with Stages Power Meters?
To help find your current crank model, check the inside of the crank arm for the model and length.
The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm Allen wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.
