1998 gt gtb

Nice one, it seems to be a bit of a pain to acquire one of these but I'd definitely love to have one some day.

1. rims - can't go wrong with boxed so depending on budget tb14 / opcd / excursion for example. if you wanna get silly, put that trispok you have lying around to use
   
2. definitely keep the seatpost if that supertype is the alternative haha
   
3. I don't know what kind of cockpit you're looking for but I'd go for pro chrome + carbon risers.
