the disc tab has been the most annoying part of the frame, having specified that i want the option to run a rear disc, it seems although there is physically not enough space to fit the calliper.
Fucking disc tabs. You wouldn't believe how many I come across that are just wrong. Usually it's alignment rather than simply not being able to put a caliper in, but it seems mass-producing Taiwanese and local custom builders face the same challenge. Some brakes/calipers/lever combinations rely on ridiculously close tolerances (the current trend in cyclocross bikes with disc brakes is like a perfect storm of shitness) and it seems that it's hit or miss. Avid's patent of v-brake style conical washers certainly helps, but even then it's not perfect.
