Rene Herse Fender Eyebolts


Many of Rene Herse’s most coveted bikes used fender eyebolts with round heads and matching rounded cups: more elegant, lighter and (slightly) stronger than the large angular heads on current eyebolts.

We custom-made these eyebolts in three lengths: 7 mm (stay to fender connection), 11 mm (stay to unthreaded dropout connection), and 20 mm.

7 mm and 11 mm eyebolts sold in sets of 4.

20 mm eyebolts sold in pairs.

Pro Tip: The 20 mm eyebolts are extra-long and designed to be shortened to fit your application. Thread a nut onto the shaft before cutting off the bolt to restore the threads after cutting and filing.

These eyebolts also are perfect for restorations of Rene Herse bikes from the 1940s and early 1950s. By the late 1950s, the rounded eyebolts no longer were available, and Rene Herse lacked the resources during the downturn of the cycling industry to make his own, so he used standard squared-off eyebolts instead.
