Hubs

Shimano's 105 Front Hub is an excellent beginning to a strong, light front wheel. The diamond-polished bearing races mean the hub rolls super smooth and the labyrinth seals shut out dust, dirt and water. Plus, the cold-forged-aluminum hub shell is beautiful and built to last. You get Shimano's excellent quick-release skewer, too.
