Fit perfectly, easy to install

These just fit perfectly. They were super easy to install, took about 5 minutes. Be sure to keep the spacers you remove, in case you decide to remove the mud guard. Once installed, this thing is solid. No movement, no vibration. It just works.

Clean look
by Anonymous

The mud guard has a nice clean / discrete look. Works well against mud and water. Does not interfere with bike racks that clamp to the front tire.

I like that it will stay where you put it and not slide around. Also it is nice to be able to fit 29x2.6 tires
