After some estimating, I'm doubtfull that it will work. The geometry of cantilever brakes make them equivalent to road brake pull. Linear pull is an entirely different situation even when scaled down to mini-V's. Here is a drawing of how I came to my conclusion... The top is a mini, the middle is a canti, and the last is a full size. The decimals are hard to see and the actual dimensions may vary, but I think this shows the point well enough. I assumed a 1/8" gap between the pad and the rim. To close the brakes, the pads have to move 1/4" collectively. So the large V-brakes ratio is 7 to 1 cable pull, the mini-V's ratio is 4 to 1 and the canti's ratio is about 2 to 1.
