This Review Title is Should prevent long term damage to indoor trainer bike if in humid climate and the content is: Fits a motobecane 58cm road bike on my indoor trainer with no issues. I sweat loads when cycling using zwift or just doing my own training so this is handy to have. You only need to worry about the potential for rust if using aluminum or steel frame in a high humidity climate really. For preserving vintage bike frames in use this would be perfect..There are other information for this review, one is This reviewer did not purchase it and the other is 0 people think this review is helpful.
