Shimano Tiagra Front Hub

Shimano's Tiagra Front Hub is the durable, lightweight heart of a fast everyday front wheel. Super-polished cups and cones house ultra-smooth stainless steel bearings to minimize rolling resistance, and the hub's oversize aluminum shell builds into a stiff, responsive wheel. Adding to that, Shimano's labyrinth seals shut out dust, dirt and water for phenomenal durability.
