As a passing comment, I know it sounds like I'm fussy, but I just remembered how much of a challenge it is to find a frame with normal rear dropouts, that take a regular headset, that have bosses for V-brakes, that have a geometry for suspension forks and holes for a backrack... I suppose I could end up with a Nashbar mountain bike frame. In that case, I read the 18 inch might be like a 17 inch and it may be better with an 80mm travel fork.
