Ok, the Schwinn ebay frame came and went, so there is another I am looking at. My question now is, since most track bikes seem to have a similar ST-TT ratio, what would a frame with a TT about 5cm longer than the seat tube result in? 52CC TT and 57CC TT. The owner said the wheel fit is tight, but would this be too tight to be comfortable for any distance? My other bikes are +/- 54CT and 55CC, so obviously a shorter stem is in order, but is this too far out of whack? BTW, I have a longer torso than legs.

I think there's a typo in there somewhere, so here's how I'm interpreting this: the seat tube is 52 cm center-to-center but the top tube is 57cm, and your usual bike has a 54 or 55cm seat tube with a similar top tube length. If that's the case, you're looking at a 2 cm shorter ST and a 2 cm longer TT. Right?

One concern is that the further you raise the seatpost, the further from the bar the seat gets, so by compensating for the shorter ST by raising the saddle, you're also effectively lengthening the TT by a little bit, and it's already longer than you normally ride. If you go this route, be prepared to get a stem that is shorter, perhaps by 20mm or so, and that also has a greater degree of rise.

Personally, I might be able to handle a frame being either a little bit small or a little bit long, but probably not both.
