The only thing smoother than the 3/8″ UNF bolts that come stock on most G-Sport Hubs are the Volcano Bolts that are available separately. These are for pegless riders who don’t need the 17mm wrench flats, and can use just a 6mm allen wrench to tighten up their wheels.

How can it take so long to make a bolt? If we’d been happy for the production ones to be machined from bar stock like the prototypes (and to be similarly expensive) then it would have been a lot quicker, but instead we decided to invest the time and effort to make a forging tool to give the part a better grain structure and to get the price down. So here they finally are.

G-Sport Volcano Bolts:
» 3/8″ diameter
» 24 threads per inch
» 6mm allen key socket
» 24mm diameter “volcano” head.
