Shimano's 105 Front Hub is an excellent beginning to a strong, light front wheel. The diamond-polished bearing races mean the hub rolls super smooth and the labyrinth seals shut out dust, dirt and water. Plus, the cold-forged-aluminum hub shell is beautiful and built to last. You get Shimano's excellent quick-release skewer, too.

The Shimano HB-M525A hub is ideal for use with 6-bolt disc brake rotors and quick release dropouts. - Double contact sealing - Super polished bearing races for low friction rolling - 6-bolt ISO disc mounting surface

SRAM's Predictive Steering Hub is a dedicated hub interface for the inverted RockShox RS-1 fork. Ultra-durable, high-precision Speedball bearings spin smoothly in all conditions and the oversize, solid-aluminum Torque Tube axle delivers extreme strength and stiffness. It's equipped with standard 6-bolt rotor mounts and is not convertible to other axles.

Ratchet freehub bodies have a gloss finish and don't have a seal, as this is fixed on the hub shell. The Ratchet System was the first of this type for DT Swiss; used in the mid-range products like the 350 hubs.
