Longboard Rack Head Tube Mount, with the U bolt included.
There are three sizes which correspond to the 3 sizes of U-Bolts available:
Small: U Bolt fits tubes up to 1.4" / 35mm Diameter
Medium: U Bolt fits tubes up to 1.8" / 45mm Diameter
Large: U Bolt fits tubes up to 1.8" /45mm Diameter and the U bolt can handle up to a 6" / 150mm distance from the front of the head tube to the notch of weld when top and down tubes are welded together
For larger diameters, the Large U Bolt can be reshaped into a variety of sizes. We have installed successfully on up to 2.4" / 60mm diameter tubes with some creative shaping of the U Bolt. The U Bolt itself is stainless steel, so it can be clamped in a bench vise and reshaped without damaging the finish.
U Bolts are M6x1.0mm thread. Need something larger? M6x1.0mm threaded rod is readily available and can be used to make your own longer U bolt, or use M6x1.0 thread couplers to cut and reassemble the standard U Bolts.
