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.
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
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...
