I was having a difficult time on regular rollers and my bikes all have through axles now I am unable to use a regular trainer. I've used it for my warm ups for CX racing and had much better races because of it. Being in SoCal, we don't have inclement weather often but when we do, I am grateful to have this roller.
We often travel with our bikes and sometimes that involves stopping in places where I want to use a bike trainer. I saw many use this trainer for warmup at bike races so I decided to give it a try. It is fast to setup and it works well. It is compact when traveling and fits in my car much easier than trying to take a traditional trainer.
