I run 28's (tight fit), short-reach Dura-Ace 7402 brakes, and fenders on my early 90's Bianchi race bike. I made my own version of the River City Reacharounds out of rear rackt stays and set 'em up as split fenders. I've ridden them on snow-covered roads and MUP's, as well as on dry, wet and muddy paths. The only thing that's ever clogged 'em was a really wet, clay-soil trail that I had no business being on with a race bike. It was still fun though
Also, IMO anything but full coverage fenders (that include the front portion of the front fender) is pointless and frustrating on road bikes.
