SRAM's X9 hubs are built tough with light aluminum hubshells for the strength to tackle the mountain year after year. You'll love the durable high-precision cartridge bearings that spin smoothly in all conditions and the strong steel axles that are built to hold up under pressure. Plus, careful machining helps keep the X9's weight low without compromising durability.
