I am preparing for the sad fact that my Cinch spindle PM may be dead. Several years of great service, but not transmitting data anymore (waiting to hear back from RF about repair, but not getting my hopes up). In the meantime I am looking at replacements. Only thing I am seeing is the P2M chainring that is compatible with the Turbine crank I have.
While I am willing to swap cranks, the Turbine is about as bulletproof as I can get. And I have a spare crank if I break it, let alone being able to easily get more. And I would think it would be most cost effective vs getting a crank AND power meter.
This is going on my 35+ pound 170mm Enduro which I beat the shit out of, fragile parts need not apply.
