Raced one for two seasons. The geometry is fine, with the Fuji-supplied fork. If you have to go aftermarket, just get one with the same rake as the stock bike, and you'll be fine. The chainstay complexity is the bigger problem. Bummer that Nashbar is selling both good and "bad" ones, and people aren't finding out until they get their bikes.

Short head tubes are what seems to be in for track bikes these days, which is why everyone is running stems with some rise to them. The FTP is a fine track racing bike. I personally would imagine it beating the hell out of you on the streets, though. It's stiff AND rigid. The former is good, the latter is bad (but not a big problem on the track).
