I bought a 1997 GT frame. I have two Bologna type forks: a 410 mm a-c in plain gauge and a 398 mm a-c version with single-butted legs. I'm running the latter fork at the moment because it's a bit lighter. The steering feels slightly on the sharp side though. I feel that the handling with the 410 mm fork is probably closer to what was originally intended, but a 405 mm fork would probably be ideal. What axle to crown length did GT use on their 1997 rigid bikes?
