Indoor training using smart apps.
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.
As it stands I really like this product. Smooth quiet operation, easy set up, etc. Make indoor training (to keep in shape when unable to get on the road) fun.
