Head Tube Mount U-Bolt - Small, Medium, Large

Longboard Head Tube Mount U Bolt, with nuts and washers.

There are currently four 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

Large V2:  MUST BE USED WITH V2 HEAD TUBE MOUNT.  U-Bolt fits tubes up to 2.4" /60mm 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 Large U Bolts 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.
