• If the new Easton Cinch power meter measures power using strain gauges in the BB spindle, how can it measure power output from only one side of the drivetrain? That's what the reviews say it does.

  • The right crank doesn't wind up the BB spindle, the load passes directly from crank to spider to chainring. If you measure torque by seeing how much the BB spindle twists, you're only measuring torque generated by the left crank.
