I’m trying to get as close to real world power numbers on my Travel Trac Comp Fluid trainer as possible. My power numbers for a given HR (effort) are too high compared to the real world.
With the tire tire pressure at 100psi I did some experimentation with the number of turns of the wing nut in applying contact pressure from the trainer cylinder to the tire. If I apply 1 full turn my power numbers are almost double what they are when I apply 2 full turns for the same HR (effort). 2 1/2 turns seems to yield close to real world power numbers. In none of the settings is the tire slipping.
Does anyone know the recommended number of turns to correctly calibrate the trainer?
Also if I apply more than 1 and 1/2 turns the trainer is extremely and annoyingly noisy. I’m using the Vittoria Zaffiro Pro Trainer tire. Any suggestions to reduce the noise?
