I am in the market for a reasonably priced power meter.
I was looking into pedal based ones but all seems to be clipless pedals, I want to be able to ride with normal shoes.
Then I began looking into the ones that are placed on the left crank arms like stages, avio. The Shimano 105 or ultegra versions are ok around $300 however FSA specific one is ~$500. So I was wondering if I can sway FSA crank arm(see the picture) with a shimano 105 or Ultegra left crank arm (Stages)?
