I installed salmon kool stops on my 10-speed earlier this summer, because the black pads it came with (installed new at the shop when I bought it) weren't gripping enough for my liking. The kool stops definitely grip a lot better, but they make a godawful racket every time I brake (my husband said they sound like a "deranged, horny goose" -- today when I came to a stop by City Hall, a crow cawed in response). I've already tried toeing them in, roughing them up, cleaning the rims... it hasn't gotten any better. Any other suggestions? I feel self-conscious about them in the city because pedestrians hear the screech and assume that my brakes aren't going to work. Also it's annoying.
