Whether you're after a featherweight low spoke count or a stalwart Clydesdale build, few front hubs offer the all-around value as Shimano's Dura-Ace HB-9000. The hubs roll on Shimano's precise, adjustable cup and cone bearings, which enjoy the advantages of being serviceable and spreading load more effectively compared to cartridge bearings.
The hubs also feature Shimano's Digital Click Adjustment, which actually refers to your fingers, not some sort of high-tech electronic device operating in a virtual world. Once you've loosened the hubs with an Allen key, you can adjust hubs with your own fingers — no cone wrench required. The freehub body and axle are titanium and aluminum, respectively, to keep the weight down.
Finally, we noted earlier that the cup and cone bearings in these hubs are serviceable. That's definitely something you'll want to do on occasion in order to keep them running in top shape. After all, they're a lightweight, race-tuned set of bearings, which means they're capable of operating at levels that other bearings can only dream of.
