I had rollers last winter and just didn't enjoy them as much as I wanted to. I couldn't keep myself motivated to ride for more than 20-30 minutes at a time and I really didn't feel like it allowed me to get any real "distance" in because it was so much work just to stay upright. Really couldn't focus on anything else, and if I'm riding inside, I'd like to be able to focus on the TV or a school book.
