Koolstop makes "red" replacement pads for V brakes (or newer vintage canti brakes that have the same brake pads as V brakes). The reds are a close cousin to salmon, and are labeled as "all weather" braked pads. No squeal at all with the Tektro CR720 canti brakes, and I have these on my two commuter bikes which get lots of use year round. When the road conditions are dry, I use the front brake for almost all stopping and the red pads have been fairly gentle on the rim surface. Anyone ever tried the Koolstop green, which are labeled as "dry weather" brake pads?
