And sometimes discs "will not stop you" either, if you're going to be nitpicky about it. This year, after a stream crossing in one race followed by a short, steep, brakeless downhill into a rockgarden, my wet discs barely slowed me down for about 20m.
I never, once had a single instance where my v-brakes failed to stop me, racing in very wet New England as well as around the country on the norba circuit. They are capable brakes, so when people go around claiming they "will not stop you," I will argue otherwise. In most cases, I believe you would do the same (but since you are following me around rebutting all my posts, that is not the case here)
Sorry if my experience isn't enough for you.
