got this old gazelle frame and wanted to build it up as single speed. the problem is that the front cantilever sockets are only 5cm (c-c) apart from each other and have only one hole for the spring. had a similar frame a few years back and remember vaguely that i had a hart time finding brakes because modern frames seem to have more space between rim and cantie socked. would mini v brakes like the tektros work?
ps: the maximal allowed wide of a flat bar is 20" right?
any advice would be greatly appreciated, thanks
