Awesome tire fender. I use this fender on a Specialized Fatboy mountain bike and it is totally adjustable to stay clear of my 27" x 5.8" wide tires. I have to remove it to service my bike on the pro stand and this fender is super easy to quick release it and reconnect it. The fender is super wide that helps keep me somewhat mud free. After an hour in the trails on mud/snow/water, my bike is totally covered and so are my legs but there is no more strip up my back
I've been using some sort of mud flap for years on my MTB's. This is about the best so far. Still, the mounting system doesn't give a distinct "snap" or "click" when closing, and will move around on my seatpost during hard riding, despite cranking the strap down tightly.
