I always thought that my Cycleops Pro 300PT with a powertap hub in the flywheel was pretty accurate. I have done two 60 minute timetrials and the last 30 minutes always felt a lot easier. That made me think because maybe the powertap was inaccurate during the hour due the fact that the flywheel because pretty hot after 30 minutes of riding > 250 watts.
Two days ago I zero torqued before a training. After the training the flywheel was hot and my torque was 10 inch-lbs. After a couple of hours when the flywheel was at room tempature the torque was 0 inch-lbs. Yesterday before my training the torque was still 0 inch-lbs but after the training it was again 9 inch-lbs.
- My question how much does this change in torque affect my average power? Is it off by more than 10 watts?
- And is this a known problem?
