Shimano Ultegra Front Hub

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.
