Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

Yeah agreed, would probably feel happier dropping a ton on them if they were the pedals I use anyway though!

Speedplay aren't exactly cheap without power measurement to be fair.

Edit: I'm not holding out hope this thing exists / will exist, but since you suggested it!
