Building upon the already proven Duroc platform the new Duroc 30 Pro features the same trusted double-wall, welded alloy tubeless rim but is now blessed with the gift of a fast engaging and all-new Super Bubba X hub.

The Super Bubba X utilizes the same drop in ratchet ring tech as the Super Bubba but, instead of two offset 45 tooth rings, there is only one 90 tooth ring. This combined with a six pawl freehub body, results in the same engagement of 4 degrees and shaves 55g to bring the total weight of the rear hub to 285g. It also means that there are no threads within the hub shell guaranteeing you will never find yourself walking out of the woods with an overpriced strider bike.

The wheels are laced with straight pull Wheelsmith DB14 spokes and alloy nipples. The total weight of the set is 1760g and will include everything you need to set up tubeless within the box. Freehub options include HG, XD, and Microspline.
