Fork Crown Eye Bolt for Fenders and Racks (Fork Crown Daruma)
This neat little eye-bolt hooks over your front brake bolt and extends down inside the fork crown. It thus allows perfect mounting of your front fender even if you don't have a threaded fork crown boss. Very clever!
This gizmo came with my fenders, and I tried to use it to mount my front fender, but the screw isn't long enough--only one or 2 threads poke out below the rubber washer. I'm going to have to use an L bracket which is a less-clean solution, so I wish this had a longer option.
