Shimano HB-7600 Hi Flange Track Hub Rear 32H Single Thread

The HB-7600 hub features cup and cone bearings for increased strength, and easier maintenance and adjustability over sealed cartridge type bearings.

Dura-Ace is at the peak of Shimano's engineering and manufacturing expertise, and the Dura-Ace Track 7710 series of products takes all that knowledge and distils it into components designed specifically for the rigours of track cycling.

Technologies

Cup and Cone bearings:Angular contact bearings of the cup & cone type offer greater strength than sealed cartridge industrial bearings due their ability to displace lateral and vertical loads more effectively for super smooth rotation and longer durability. Angular contact bearings also allow easier maintenance, adjustability and serviceability.
