Shimano's Ultegra Front Hub is the durable, lightweight heart of a race-ready front wheel. Super-polished ball races house ultra-smooth bearings to minimize rolling resistance and the hub's oversize aluminum shell design eliminates fork flex for stiff, responsive wheels. Plus, Shimano's labyrinth seals shut out dust, dirt and water for phenomenal durability. And, you get Shimano's superb quick-release skewer, too.
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. Plus, careful machining helps keep the X9's weight low without compromising durability.
