Full details
The Shimano Dura-Ace 7600 Track Front Hub is designed for track cyclists and fixed-gear enthusiasts seeking exceptional low-friction performance and robust durability. Its key benefit lies in its super smooth Dura-Ace bearings, ensuring optimal power transfer. A potential consideration is its fixed 32-hole drilling, which may not be compatible with all rim types. This hub features a forged and anodized aluminum body with a composite polycarbonate resin shell, a 9mm hollow shaft, and a 100mm O.L.D.

FAQs
What is the primary advantage of the Dura-Ace bearings?
The Dura-Ace bearings are engineered for exceptionally low friction, which translates to smoother rotation and more efficient power transfer for the rider.
Can this hub be used on a standard road bike?
No, this hub is specifically designed for track and fixed-gear bicycles and does not have a braking surface, making it unsuitable for road use.
What is O.L.D. and why is it important?
O.L.D. stands for Over Locknut Dimension. It refers to the width of the hub, measuring 100mm for this front hub. This measurement is crucial for ensuring the wheel fits correctly into the bicycle's fork dropouts.
How many spokes does this hub accommodate?
This specific model features a 32-hole drilling, meaning it is designed to be built with 32 spokes.
Is it difficult to build a wheel with this hub?
Building a wheel with any high-performance hub requires precision. Due to its specialized nature, it's recommended to have wheels built by an experienced wheel builder to ensure optimal performance and durability.
What is the material of the hub shell?
The hub body is made from forged and anodized aluminum, with a composite polycarbonate resin hub shell.
Does this hub come with a skewer or axle nuts?
This product listing is for the hub shell and bearings only. Axle nuts and any necessary components for securing the wheel are typically sold separately or come with the wheelset build.
Troubleshooting
Hub feels rough or stiff when spinning
This may indicate contamination or wear in the bearings. While designed for low maintenance, if the issue persists after cleaning the exterior, professional servicing by a bike mechanic experienced with high-end hubs is recommended. Avoid trying to force the hub or overtighten components.
Wheel feels wobbly or untrue
This is likely a wheel build issue, not a hub defect. Check spoke tension and rim condition. The wheel will need to be trued by a qualified wheel builder.
