Both the hub and freehub body have evolved to designs that improve rigidity for efficient power transfer and quick handling. The bearings have been updated with a new tool-free bearing adjuster for quick bearing adjustments. The freehub continues with the durable titanium shell and quick engagement internals.

• Click adjust system: for quick and easy adjustment by hand without use tools
• High axial rigidity: enhanced rigidity for better rotation even when quick release is tight
• Titanium freewheel body: extra light, extra rigid
• 8, 9 & 10-speed compatible: quick engagement enables faster acceleration

While the grade of materials and the surface treatment of the races may change between groups, one thing is constant. Shimano hubs exclusively use a cup and cone bearing system in all of its hubs. Cup-and-cone bearings offer greater strength than sealed cartridge bearings due to their ability to displace lateral and vertical loads more effectively for super smooth rotation in real world riding conditions. Cup-and-cone bearings also allow for easier maintenance, adjustability and serviceability.

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 and are lighter and operate based on a symmetrical fulcrum lever. An evolutionary refinement to offer more performance and reliability.
