I have a fluid trainer that I use in the winter, but I've never used a roller. What I have heard, though, is that trainers give you more of a resistance work out and rollers are more for spinning and technique.

I bought a fluid trainer last year with a five-level resistance setting. The top levels can really give a workout. I do not see rollers with resistance levels on them.

So, there you have my uneducated opinion... TRH
