    Simple to test; - Place the bike upside-down. - Spin up the wheel. - Using a pen or object with a similar blunt point hold it as close as you can to the wheel without it touching. - Look closely for relative movement at the edge of the Rim. Anything more than a couple of millimetres change in radius from the axle will have an adverse effect on a Turbo Trainer where the measurement from the Axle to the Roller is always constant. Sideways movement is more acceptable on a Turbo Trainer as long as the tyre always sits within the Steel Central-portion of the Soft-Gel Roller.
