SunRingle Düroc LE SD37 PRO 29″

Introducing a limited edition of our Duroc Pro SD37 wheels equipped with 3D Violet anodized Ringlé Super Bubba hubs paying homage to the original Super Bubba’s of the past. The new Super Bubba’s have evolved to a state-of-the-art hub featuring our Clock’D dual-adjustable ratchet ring technology. Clock’D allows the rider to adjust the 6-pawl system from 8º of engagement for heavy-duty use to 4º of quick engagement for technical riding by simply offsetting the keyed ratchet rings. To keep things strong and durable the hub shell is forged then machined out of lightweight 6061 aluminum and is paired with a stout 7075 aluminum axle. Symmetrical front endcaps, tool-free service, and one size (6902) bearings used throughout make maintenance a breeze.

Laced to our race proven Duroc SD37 rims, featuring straight pull spokes and alloy nipples these wheels were designed to withstand the gnarliest conditions. The ultimate rim strength of our Duroc SD37 rims comes from the careful combination of bead hook width, sidewall thickness, and spoke bed thickness. Whether you’re on an enduro racetrack or poking a whip out a bit father than you can bring back, you can rest assured that your Duroc SD37 rims will provide you with the strength you need to hit lap after lap until you get it right.

As a bonus, we’ve included both an XD and Microspline freehub body, torque caps, tubeless valves, and sealant in the box for easy swaps without needing to purchase additional items.
