Hubs

Shimano's Ultegra Hubs are flag-bearers for high-durability, smooth-rolling performance. Hardened steel cup-and-cone design use stainless steel bearings for minimal drag and superior ease of maintenance. Shimano's Digital Adjustment System makes hub maintenance fast, simple, and reduces axial force on the bearings, reducing wear and tear on the hub internals.

- Internal gear 8-speed hub with 70mm drum brake - Rotary gear selection with no protruding indicator chain or switch box - Direct drive in first gear allows use of smaller chainwheels - A356 aluminum hub shell with 13/32" slotted solid axle (185mm overall axle length) - Gear ratio range of 325% - Includes 3-spline 23 tooth cog and a TSS86 twist shifter. Brake lever sold separately

Converts a Stan's 3.30/3.30Ti rear hub to a 12mm thru-axle. Compatible with both Type 1 and Type 2 rear hubs.

Focus on the ride, not your gear with SRAM's Automatix 2 Speed Hub. A centrifugal clutch in the hub automatically changes gears based on your speed, and a coaster brake takes care of the stopping so there's no shifter, no cables, and no nonsense. All you'll have to do is sit up and enjoy the ride!
