get the 29 inch comp...be a rebel

what's that even mean? Pro / Disc / Comp?

disc means disc brakes...pro means the top options/accessories, comp is short for competition, so "medium" options/accessories

if it doesn't have those, it means it's pretty basic

well.. I'm certainly not a professional.

at least that's how I understand it...tim'll correct me if i'm wrong

hausevangelist , you're mostly correct. lilcompanion. nice choice bike. might want to look at the Giant & Trek versions
