Project 321 CX1 Rear Hub 142mm Quiet Pawls Sram Xdr



The Project 321 CX1 Rear Hub was designed with Cyclocross and gravel grinders in mind. Essentially, it is their well-designed G2 Hub with some tweaks to allow the compatibility to run a SRAM 11/12 speed cassette. This means you can keep riding drop bars and integrated levers and get all of the benefits of Project 321 exquisite hubs. You still get all of the great features such as a revolutionary drive system, high capacity oil chamber, angled flanges, brilliant finishing, tension adjustable axle, and high quality bearings. All Project321 rear hubs are now equipped with the new magnetically actuated, 6 pawl, ratchet drive system. This new system gives you a combination of options and features like no other drive system on the market. The angled flanges allow the spokes to touch the hub only at the bend and nowhere else. This creates a more stable and true wheel and eliminates any unnecessary stress on the spokes. Rotor bolt holes are form tapped which creates a stronger, cleaner thread than the more common method of cut tapping. 10 years on hub shell and axle, 3 years on pawls, drive ring, and free hub body and 1 year Enduro bearing warranty. (For original owner only; does not apply to anodize fading). Project 321 hubs feature a CNC engraved logo and comes standard with 2 high precision Japanese cartridge bearings. Available in all 10 color options with long lasting anodization. Made in the USA.
