The Shimano Dura-Ace HB-7600 is a legendary front track hub built for velodrome competition and high-performance fixed-gear riding. Favoured by Keirin professionals in Japan and track enthusiasts worldwide, its hi-flange forged aluminium construction delivers exceptional lateral rigidity and precise, responsive handling under sprint efforts.

Highlights

• Hi-flange forged aluminium body: Large flange diameter maximises spoke bracing angle, delivering superior wheel stiffness and lateral rigidity for track sprinting.
• Chrome-plated steel axle: Robust 9mm axle with 100mm over-locknut distance suits standard track fork spacing and resists corrosion.
• Borozon-treated bearing races: Hardened races paired with stainless steel balls deliver smooth, durable rolling with minimal friction.
• 32-hole drilling: Versatile spoke count suitable for training, road-to-track builds, and everyday track use.
• Keirin heritage: Trusted by elite Keirin professionals and used in Japan's highly regulated velodrome circuit — a benchmark for track hub quality.
• Flanged track nuts included: Ready-to-build with the hardware needed for secure axle retention in track fork dropouts.

Dura-Ace Track Engineering

The HB-7600 sits within Shimano's Dura-Ace Track 7710 groupset, a line purpose-built for velodrome and fixed-gear applications. The hi-flange design reduces spoke length and increases the lateral bracing angle, producing a stiffer wheel that responds immediately to power input — critical for standing starts and sprint finishes on the track.

Compatibility & Fit

Designed for front track forks with 100mm O.L.D. (over-locknut distance). Axle diameter: 9mm. 32-hole drilling — pair with a compatible 32H track rim. Radial lacing is not recommended and may void the warranty; cross-lacing patterns should be used. Part of the Shimano Dura-Ace Track 7710 / 7600 groupset family.
