Thanks a lot! Theres a lot of good info there. I'll do some studying for sure.

I do have a question about fit/sizing however. How does one know if a bike fits well? Do bikes come in sizes? If so, what are they? I'm 5'6 with a skinny build, what size range should I be looking at?

Sorry for the barrage of questions, I'm sure someone here has a link to explain it all, thanks again!
