or the brakes themselves? I'd have to disagee either way. There are Avid DBDG (old name for the BB7 brakes) that are going on 5 yeas old and still going strong. As for the brake pads, I can easily get double the life out of my disc brake pads (often tripple) than I can with my v-brake pads. The bottom line here is application and the conditions the brakes are used in. For off road I won't ever go back to rim brakes. My summer commuter has v-brakes and they work geat. But the winter beater and my off road bike have discs!
I had no idea this was such a touchy subject.I guess both have their place while disc can work better ,the weight and simplicity of v brakes are still preferred by some although they seem to be getting phased out.
