My stock fork has a steer tube length of 180mm from the bottom of the bearing race (which is pressed on) to the end of the threads, and there are two spacers used stock. The replacement forks come in 175mm and 200mm.
Should I get the 175 and take out a shim and figure it will grip enough threads to be fine or should I go with the 200mm and either slice off 5mm and rethread the end or add more spacers (looks goofy)? I'd imagine there would be enough threads to use a slightly larger one and I could always have the threads extended and the LBS.

Best to go long?
