Shimano Dura-Ace Track HB-7600 Front Hub

While the HB-7600 is engineered specifically for the demands of track cycling, its robust construction and sealed-bearing reliability make it a popular choice for fixed-gear street builds. Just keep in mind that it uses a solid axle, which requires a wrench for wheel removal rather than a quick-release lever.

NJS certification indicates that the component meets the strict quality and safety standards required for professional Keirin racing in Japan. If you are building a bike for sanctioned track competition, this certification ensures your equipment is compliant with official regulations.

Borozon treatment is a specialized finishing process that creates an exceptionally hard, smooth surface on the bearing races. This reduces friction and wear over time, resulting in a hub that spins with minimal resistance and maintains its precision feel even after heavy use.

No, the HB-7600 features a solid axle design intended for use with track nuts. This setup is standard for track cycling to ensure maximum security and rigidity under high-torque sprinting conditions.

The hub has a standard 100 mm spacing, which fits most road forks. However, because it uses a solid axle with track nuts, you will need to ensure your dropouts are compatible with a bolt-on axle rather than a quick-release system.

The high-flange design increases the bracing angle of the spokes, which significantly improves the lateral stiffness of the wheel. This is particularly beneficial for track sprinters who need a wheel that resists flexing during intense, high-power efforts.
