Solidly built and pretty easy to install. Big enough to accomodate my 35mm cyclocross tires (small tread for dry conditions - not sure that I could run big knobby mud tires)
Needed some fiddling around with on a shakedown ride to get aligned just right, but that was a simple task using an 8mm spanner.
My only (minor) aggravation was that I lost one of the small rubber caps for the end of the stays that connect fender to frame. Doesn't affect performance - purely cosmetic.
