New Sheriff hubs are the ultimate in track racing hubs. They minimize weight with larger cutouts in the flanges, lightened axles, shorter bolts, and slimmer end caps than previous versions. The result is a hubset that weighs a mere 432g, 198g for the front, and 234g for the rear. This makes it one of the lightest track hubsets in the world, a figure even more impressive when you consider that All-City didn't eliminate the usefulness of a fixed / fixed or fixed / free option as most racing hubs do. They feature the finest Japanese manufactured 6902 bearings which roll incredibly fast and smooth while retaining excellent seals for all weather, all-day everyday durability. Front hub specs: - Weight: 198g - Torque Spec: 33nm (25ft lbs.) - Non-Drive Side Center to Flange: 34mm - Drive Side Center to Flange: 34mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm Rear hub specs: - Weight: 234g - Torque Spec: 33nm (25ft.lbs.) - Non-Drive Side Center to Flange: 29mm - Drive Side Center to Flange: 29mm - Non-Drive Side Flange Diameter: 62mm - Drive Side Flange Diameter: 62mm

The number to count on—240 with Ratchet EXP. The new 240 is developed for riders with the most extreme ambitions. The latest version of the hub is equipped with the Ratchet EXP system to maximize reliability. The increased bearing distance increases bearing lifetime, the straight spring provides more direct engagement (which reduces wear), and a smaller number of parts not only makes maintenance easier, but also reduces weight.

R45D hubs combine a lightweight hub body, our legendary made-in-house bearings, and a six-bolt rotor mount to harness the power of disc brakes.

Our bearings, available in steel and ceramic, have heat-treated, surgical-grade steel races that are machined simultaneously, with tools of equal wear to ensure perfectly matched inner and outer races. The quality and speed of our bearings is what sets us apart from the competition and they are what you will feel and notice on every single ride.
