So... I don't think my power meter feels 20% off. But 2.5 years ago I climbed Old La Honda in 18 minutes at 4.57 w/kg. Yesterday I climbed it in 22 minutes at 4.57 w/kg. W.T.F. Is there any way in hell that my bike or my form is losing me 60 watts? It's stages now vs powertap then, but I know there is no way I was only putting out 260 watts.
