Ingeniuosly simple way to mount fenders to bikes with recessed brake bolts.

Mounting fenders to bikes with road calipers is a real pain in the arse. Fickle creatures, the calipers become difficult to adjust once the fenders’ tab is stuck on the backside. Enter the late Sheldon Brown. One of Problem Solvers true heroes, Sheldon gave the idea for the cleverly named Sheldon fender nut. Basically, the Sheldon nut replaces your caliper’s brake nut, but also contains threads for standard M6 bolts. This allows you to install and remove the fenders without messing with your brakes.
