Product details
Building on the already proven Duroc platform, the new Duroc 30 Pro features the same reliable double-walled, welded tubeless aluminum rim, but is now equipped with the quick-responding and brand-new Super Bubba X hub.
The Super Bubba X uses the same ratchet ring technology as the Super Bubba, but instead of two offset 45-tooth rings, it has a single 90-tooth ring. Combined with a freehub body featuring six pawls, this results in the same engagement of 4 degrees while saving 55 g, bringing the total weight of the rear hub down to 285 g. This also means that there are no threads in the hub shell, ensuring that you will never leave the woods with an overpriced Strider bike.
The wheels are laced with Wheelsmith DB14 spokes with straight pull and aluminum nipples. The total weight of the set is 1760 g and includes everything you need to set up tubeless. Freehub options include HG, XD, and Microspline.
