From manufacturer's official website:

The new Record™ hubs have been substantially redesigned to exalt the qualities which made the previous ones famous and appreciated all over the world.

The oversize body design has been accentuated, some parts have been lightened and the freewheel body is made entirely of light alloy. The highly appreciated adjustable 15-ball bearings have remained unchanged and the ceramic ball kit is available as an option.

The quick releases have been redesigned completely; they are now lighter and their operation is based on a symmetrical fulcrum lever. An evolutionary refinement to offer more demanding users the ultimate in performance and reliability.

Light alloy axle and body - adjustable bearings - quick-release with aluminum lock nuts - O.L.D.: 100mm

Nominal weight: 116 g.
