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 ne plus ultra for performance and reliability.

10s - light alloy body, axle and one-piece freewheel body - adjustable bearings - quick-release with aluminum lock nuts - lockring thread 27x1 - O.L.D.: 130mm.

Nominal weight: 231 g.
