Darius- Your geometry link didn't open for me so I'll respond to your written questions for now. Lugs should be able to accomidate a degree of change without too much effort. The deeper sockets will be a bit more a challenge but doable. However I'd recommend that you start to get profecient with brass as it will fill the potential gaps (that come from angle manipulation) better. The front center length is very short. Depending on crank arm and foot dimensions expect around 2+cm of overlap, this is a lot. Worse if you use fenders. As a rider that track stands a lot while in traffic and uses fenders on my commuting bike, I wouldn't tollorate this much overlap. I don't know what your head angle, rake, tire radius are so i can't recommend here but a slacker steering geometry will help extend the front center. Please keep us in the loop as to your progress and have fun, Andy.
