Re: Oops (used wrong crank length PowerTap P1’s) [johovishta]
Your recorded numbers will be too low. Same force, shorter crank = lower torque = lower recorded power.

It’s a linear relationship, so your readings are 1.4% too low.

If it matters (e.g. you were doing an FTP test), you can adjust the .fit file on fitfiletools.com

Otherwise, I probably wouldn’t bother.

[Note: I misread the original post and got this back to front, so have edited to correct!]
