They're 45mm wide, designed for 700c and 27" wheels, and work with tires up to 35mm wide. Included is a hardware kit to work with almost any type of mounting in the same finish as the fenders.
Velo Orange fenders are designed to be full coverage, which means that you and your bike's drivetrain will stay clean of road muck and grime. Both front and rear fenders have full wrap around the width of your tires to eliminate spray in all directions.
Please note: Most if not all of the hardware you need for the installation of these fenders for the vast majority of bikes is included but beause the kit is as universal as possible, you may need one or two bits of hardware for your particular build. Watch this video and read the instructions to make sure your frame and fork has the correct mounts and hardware needed. If you need additional hardware, check out this page.
