I have a CrossCheck that I've been using for commuting for awhile now and while it's fine for that purpose, there are some things that I would change, particularly if I intend on giving cross racing a try. First, I have longer legs and a short torso, and the CrossCheck's shortish head tube allows me to show off my spacer collection and my wife's old Profile Boa stem. I've seen the Kona JTS frames on closeout and would like to keep the rack functionality for commuting, but be able to ride the bike in races as well. I'm currently on a 54cm CC and the length of the cockpit seems to be correct. Would I be okay on a 54 JTS or would a 56 be more appropriate? I have a 31" inseam and height wise, the CC seems to be right on. If I could just make the head tube longer and slope the TT... :mad2: Any help would be appreciated.
