This is from Shimano’s top of the range racing group set, designed for the track.

The Dura Ace track front hub is lightweight but strong, and rolls along on a super polished cup and cone configuration with stainless steel ball bearings.
Ball bearings are able to displace lateral and vertical loads more effectively, and also allow for easier maintenance.

These hubs not only look robust, they are robust.
The spoke hole configurations are 28, 32 or 36 hole.
The finish is the same anodized finish used throughout the Dura Ace track group set, and the weight is 203g.
