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.
