The Shimano Dura-Ace Track HB-7710 is Shimano's flagship front hub for track and fixed-gear racing. Built from forged aluminium with a high-polish silver finish, it delivers the combination of low weight, torsional rigidity, and bearing precision that sprinters and endurance track riders demand. NJS-approved in 36-hole configuration, this hub meets the strict standards required for official Japanese track competition.

Highlights

• Forged aluminium body: Lightweight yet rigid construction handles the explosive sprint loads of track racing without flex.
• Cup-and-cone bearings: Shimano's adjustable cup-and-cone system delivers ultra-smooth rotation and allows precise bearing adjustment for long-term service life.
• NJS-certified: The 36-hole model carries the NJS (Nihon Jitensha Shinkōkai) stamp, satisfying the requirements of official Japanese Keirin racing.
• Precision-machined steel axle: The solid 9mm steel axle provides exceptional durability and stiffness under repeated sprint efforts.
• High-polish silver finish: Classic Dura-Ace aesthetic that resists corrosion and pairs with chrome or silver build components.
• Low-flange design: Optimised for radial or cross-laced spoke patterns suited to track wheel builds.

Track-Ready Engineering

The HB-7710 was engineered specifically for the velodrome. The forged aluminium shell is machined to tight tolerances, and the cup-and-cone bearing system allows trackside adjustment so riders and mechanics can dial in bearing preload to perfection. Unlike cartridge-bearing hubs, the cup-and-cone design is fully serviceable with standard Shimano cone spanners — a critical advantage for racing teams who need to rebuild wheels quickly between events.

Compatibility & Fit

Front hub with 100mm over-locknut distance (OLD) and a 9mm diameter solid axle — fits standard track fork dropouts. Laced to 36 spokes. Supplied with track nuts for secure axle retention. Compatible with all standard front wheel builds for track, fixie, and NJS-specification Keirin racing.
