I recently purchased a rear rack/fender combination and no longer require this detachable fender (an SKS X-Tra Dry Rear Bicycle Fender). This fender clips on to the seatpost of almost any bike. It kept me nice and dry over the rainy winter months. The fender was gently used for only 3 months. The campus bike shop charges $20 for it new, so I'm asking for $10 obo. Happy cycling.
