I have been unable to get a reply from Race Face over the past two months and am looking for some support and advice from you.
I have a Race Face Cinch power meter which I have been using for 3 months now. When first installed I was getting calibrations of -6 (whatever unit this is). Every few days this calibration would drop a point or two until it hit -19. Once there it has held steady at -19.
This calibration value has not changed since hitting -19 through multiple chain ring swaps, 10-35 degrees c, 900-12400 feet in elevation, and calibrations every ride.
The power outputs don’t seem wildly off but I am skeptical that the calibration steadily migrated and then suddenly stopped at one specific value. Is it possible that the Race Face power meter maximum cal level is -19 and it is simply holding steady there? Does this sound normal to you? Am I reading too much into this?
