Our Axle Cups do not have any wobble or play, therefore the bicycle will not rock from side to side.  Other trainers have noticeable movement in the axle cups resulting in bicycle instability.  We provide a tool so the cups can be tighten correctly.  We provide a quick release skewer to assure that our trainer will work on your bicycle.

The 1up No Wobble or Play Axle Cups are just one of the features that shows that we have the World's Best Performing Trainer... Guaranteed!
