Yes, but not as well as full fenders. They won't keep your pant cuffs dry, if that's what you're asking. But neither do full fenders. I don't ride in the rain much, so they're mostly for puddles, wet pavement and whatever the road might throw in my face, this is New York after all. I know what it's catching, it's right there, stuck to the other side. And like I said, they rattle a bit on bumps. My rear fender has to be adjusted so that when it swings forward from shock, it slides under the bullet nut on the rear brake instead of hammering it. I'll be shortening the rear stays at the next pass. I'd be using full fenders if they fit; those look so much better. (BTW, I passed on the brake bridge mods because there again, it was extra weight and parts that I didn't want to deal with.)
