Hello, I just recently bought a powerpod v3, haven't had the opportunity to try it yet. One thing I've wondered for some time is how much energy gets lost in the frame, pulleys etc? I guess i can be putting 500 watt into the pedals but powerpod would only record 450 since it doesn't take into consideration friction and a soft frame?
Best regards Christian

Re: Power transmission
Tests conducted by bike manufacturers through the years suggest a loss of about 2%. So, if you're pushing 500W at the pedals, the drivetrain/frame loss would be about 10W.
PP uses the 2% loss in its calculations.

Re: Power transmission
Thx, how about the friction between the tires and road surface? Guess the numbers varies if the surface is wet?
Re: Power transmission
This difference is even smaller. You'll get only about a 1% change going from normal to super-slick tires.
