SRAM's 506 hub borrows technology from its more expensive brethren to bring you a solid hub at a great price. An aluminum hubshell with hi/lo flanges provides no-nonsense durability and even spoke tension. Dependable cup and cone bearings with polished races roll smooth for the long haul and a strong, steel quick-release axle holds up under pressure.
