Shimano HB-RS770 Disc Center Lock Front Hub for 12 mm Thru-Axles

The HB-RS770 Disc Front Hub by Shimano - For 12 x 100 mm thru-axles

The Shimano HB-RS770 front hub has been developed for road bikes with Center Lock disc brakes and 12 x 100 mm thru-axle. It has a neutral Shimano logo, but is at about the Ultegra level. It consists of an aluminium body and an aluminium axle and therefore weighs very little. The proven Shimano cone bearing and high-quality seals are a matter of course. Remarkable is the two-tone design with silver shell and black flanges.

Technology:

Cup and Cone Bearings
Angular contact ball bearings of the cup & cone type are superior to sealed cartridge bearings in terms of load carrying capacity, as they distribute lateral and vertical forces better, and thus run particularly smoothly and last a long time. They are also easier to adjust, maintain and replace.

E-Thru
E-Thru is a tool-free thru-axle system from Shimano that optimises the stiffness-to-weight ratio and ensures easy handling via its reliable internal cam mechanism. It is characterised by a high torsion resistance and thus also supports cornering at high speed. E-Thru thru-axle hubs and thru-axles are available in the corresponding over locknut dimensions for front and rear.
