Picked this up for my CX bike that doesn't have fender mounts as I ride this bike in the wet off season and gravel rides so looking for something unobtrusive yet solid. Design is well thought out and keeps spray from my face and water bottles. Straps keep the fender snugly in place when mounted properly (watch for front wheel overlap) and looks stylish to boot.
This little lightweight mudguard mounts on the down tube and can be fairly easily snapped on and off the bike once you determine the placement of the mount. I use it together with a short MuckyNutz fork fender. They overlap each other by about 12 an inch but don't rub, so it gives me the coverage a full fender would from the head tube and back, if that makes sense (not front coverage over the tire like a full fender would. Seems sturdy but yet light enough that I just leave it on the bike all the time during the winter. Mine is mounted on a gravel bike running 650b x 48mm tires.
My road bike has tight clearances, so traditional fenders don't mount easily on it. This snap on fender requires a little fine adjustment and trimming to prevent contact with my front wheel when turning sharp angles, but once I dialed it in I've had no trouble. The detachable fender is a smart design, once you get the mounting bracket in a sweet spot, you might want to leave it in place throughout the winter or rainy season. Protection from road spray isn't perfect, but much better than riding in the rain with nothing up front.
Easy to put on & take off. I don't ride in the rain but even going thru puddles, I make sure I am going straight. Even then your feet will get wet. Almost any type of turn will get your legs & shoes wet. Kind of what you would expect since it is not attached to the forks.
We bought these for my daughter who has to ride to work regardless of the weather. This has been a rainy summer so she needed fenders and rain gear given the frequent thunderstorms to and from work. These fenders have built in snaps so the fender part can unsnap and fold up. The whole thing - both front and back fenders - take up very little room in her backpack such that she can carry them all the time as she commutes. When it rains, she can deploy them in a matter of seconds. They are really effective fenders too.
I know of no other fender that is this compact, this easy to store, as durable and is as effective as these. Perfect for commuters, where you have to lock a bike and are worried about theft of accessories, around universities, etc...
Works well, and if you don't cut the strap off too short, you can switch easily to bikes with larger down tubes. I am able to fasten well with that little extra strap under the fender
