Compass René Herse Stem/Seatpost Bolt
One of the things that makes René Herse bikes special are the custom-made screws and bolts. This practice came from his aircraft background: During the early 1900s, there were no standards for bolts. Aircraft makers made their own screws to ensure they were strong enough. A bolt failure on an aircraft can have devastating consequences!
The aircraft builders designed their own head shapes, so mechanics in the field could immediately see if a bolt had been replaced by a generic one of potentially inferior quality.
Drawing on that tradition, Herse made his own bolts, too. The triangular heads for his M6 seatpost binder and stem bolts are truly iconic. We now offer replicas in both lengths found on Herse’s bikes.
