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.
