The Extralite HyperFront hub is one of the lightest disc hubs ever made. When paired with the Extralite HyperRear, the hub set weighs an astonishing 246 grams (lighter than most rear hubs alone), which allows for the building of an exceptionally light wheelset. However, nothing about this hub is micro. The front hub uses two 6803 bearings and a large 17mm axle. The hub body is 7075TX aluminum, anodized black, with laser etched graphics. The hub flanges utilize a straight pull spoke system.
