If they're not for canti/V-brakes, then they're for rollercam/U-brakes. time to go to ebay for a sweet set of WTB rollercams, or a cool and quirky IRD rotary brake.robriw3 said:Have an unbuilt GT Xizang frame, was wondering what type brakes work with it. The bosses are much higher than on a standard frame. My cantilever or V-brakes don't line up with the rim.
...belay my last comments on the option of a rollercam or IRD rotary brake. Because of the boss location directly behind the seat tube, you're pretty much limited to a U style brake, shitmano's, diacompe's or others. You'd have to drill a hole thru the seat tube to use a rollercam or rotary brake, since these don't use a straddle cable that can loop around the seat tube. For those you'd need a way to give the cable a straight shot at the center of the brake, thus the need for a hole.beria said:I remember old GT frames used to have U-Brakes.
