Help I need some advice! I'm looking at purchasing a crank power meter, but it seems to be a minefield of compatibility issues. I have a Miche chainset whith a campagnolo group set, the BB is an EVO Max and the size stamp(I think) is BC 1.37" x 24 T I've no idea what this means! I was looking at a stages power meter but they're Shimano,SRAM or FSA are any of these compatable with my set up? I could go down the Garmin Vector route but these are lot more expensive. Are there any other power meter solutions I could go for?
