i rocked the zefal fenders on a french conversion for a while - until the rear fender snapped in half - the bracket that attaches the fender to the chainstay bridge slipped/popped off and the fender slipped around and under the tire....
they were mounted with zip ties, as my frame's eyelets aren't threaded, which didn't do me any justice when the aforementioned bracket failed. that being said, they offer a fair amount of adjustability in fit, offered good protection from rain and road sludge, and are narrow enough to fit my frame fairly well. i roll with 23's, and the 35mm fenders barely had enough clearance to not rub - but any wider wouldn't have fit my frame...
i've also rolled some of the freddy fender's, but the mudflap created a bit of a problem for me - i'm a little feller, ridin' little feller frame sizes - the mudflap exaserbated an already present toe overlap issue
good luck!
