I have two PowerTap G3 wheelsets. 1 Training and one with a ENVE 6.7 for racing. The training wheel stays on the road bike and the carbon wheel on the TT.
I have a suspicion that the hub on the carbon wheelset is reading slightly high (about 30-40 Watts). My reasons for thinking this are:
1. My RPE doesn't match the power output shown.
2. 2 Fairly comparable rides on the road bike and TT show same average power and NP but same average speed (the road bike is an old Trek 1.1 and the TT is a NP3) so surely the P3 would be faster?
3. When I run a ride on the P3 through BBS AeroAnalyser it comes out with a much higher CDA than the road bike.
Has anyone else had one of these slightly off? Googling it shows lots of people where it has been way off (either reading 50W or constantly over 500W).
I am in the UK so only service option is to send to Paligap for a service. I had thought about spending an afternoon doing some runs and swapping the wheels between bikes and then studying the data. Or should I just send it back for a service? My season has finished so I can live without the carbon wheel for a few weeks.
