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

But it's not accurate that's the point. And at a price point not far off P2M and greater than Powertap. Why buy it.

If you ride a discipline where you swap wheels PT rapidly loses its appeal.

So then stages competes head to head with P2M.

P2M is more costly and I cannot move P2M between tark, CX, everyday and wife's bike.

However if it turns out Stages has habit of being inaccurate and inconsistent then that's a big deal. I shall wait and see.
