This might be tangential, but here's an observation I made recently while playing with Canti brakes. When the cable stop is mounted on the stem (ie farther from the brakes), the setup becomes more squeak-prone as compared to a fork mounted cable stop. I was intrigued and changed around the cable stop a couple of times without changing anything else with the brakes. It squeaked repeatedly more with stem-mounted. I can probably reduce the sound or even eliminate with better toe-in pad adjustment, but the bottom line is fork-mounted cable stop setup is more forgiving.
