Shimano Dura Ace Rear Hub FH-7900 compatibility and specifications

Shimano Dura Ace Rear Hub FH-7900

The legend of Dura-Ace once again sets the industry standard. Created by definitive Shimano engineering and the latest technology, the new 7900 series Dura-Ace mechanical road group provides the ideal synergy of lightweight, durability and overall performance.

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
