I have no idea what to look for in a foam roller for a cyclist. As a matter of fact, I had never really considered one until this year. I'm having some SI joint pain. Additionally, after using my trainer all winter, I'm continually pulling muscles (quad and calf) when running/playing soccer. After some research, I understand that ONLY cycling will cause issues with tight muscles when performing other athletic activities and that a post-ride stretch routine along with said roller will be of some benefit.

I'm looking at some on Amazon but I just don't know what to look for, what size, does it need ridges/texture, etc...

I saw the following at a marathon expo yesterday and it looked extremely easy to use on my lower back. Would this work?
