Sackville Mudflappers

They don't work any better than duct tape, but if you're looking for the least expensive way to join the Sackville Clan while simultaneously classing up your bike, you can stop your search here. Dark green or grey-grid each with a reflective strip of 3M Scotchlite. Two grommets. Ream or drill a hole, attach with zip-ties (not included) or twine or wire or you name it. They won't last forever, but thirty years wouldn't surprise any of us.
