Thanks for your replies! I feel like I am going at all this blindly, I hear what one sales guy tells me and I think it is gosple.
I am also going to look at a Panasomic (no idea what kind) at the end of the week for $150, owner says it has had an overhaul by a bike guru.
All of this was brought on by my decision to ride in the MS150 between Houston and Austin this April. I have wanted to do this every year and have no excuses not to anymore. I just want to ride. I can't wait! I need to do this for myself.
