This road bike hub is a core component designed specifically for cycling scenarios where lightweight and high efficiency are prioritized.

Crafted from 6061+7075 aluminum alloy, it weighs only 284g, achieving lightweight while ensuring structural strength. The straight-pull design enhances wheel rigidity and transmission efficiency, and it comes with optional steel ball bearings or ceramic bearings, catering to both daily use and high-performance needs.

It is compatible with rim brake systems and lightweight road bike spokes. The 20/24-hole design balances wheel strength and lightness. Supporting various freehubs such as Shimano HG/MSR/N3W/XD, along with the standard size of 9*100/10*130mm, it is widely compatible with mainstream road bike models and shifting systems. The quick-release design improves the convenience of installation and maintenance.

Overall, it is a road bike hub that integrates lightweight, high efficiency, and strong compatibility, ideal for road cycling enthusiasts looking to upgrade their wheelsets.

Product Features and Advantages

Adopting 6061+7075 aluminum alloy composite material, it achieves an extreme lightweight of 284g, effectively reducing riding burden. Meanwhile, relying on the high strength of 7075 aluminum alloy, it can withstand continuous stress and impact during road riding. Compared with similar products, it balances "lightweight" and "strength" more perfectly.

Efficient transmission with optional performance:

The straight-pull design reduces spoke deformation, improves wheel rigidity and power transmission efficiency, making the force application more direct and the response more rapid. It offers two options: steel ball bearings (economical and durable, suitable for daily training) and ceramic bearings (low friction, high smoothness, suitable for competition scenarios), which can meet different budget and performance needs and flexibly cope with diverse riding scenarios.

Full-scene compatibility with no adaptation threshold:

It is compatible with rim brake systems and lightweight road spokes. The 20/24-hole design finds a precise balance between lightweight and wheel strength. Supporting mainstream freehubs such as Shimano HG/MSR/N3W/XD, combined with the standard size of 9*100/10*130mm, it can be widely compatible with most road bike models and shifting systems, and can be installed without additional modification, reducing the use threshold.

Convenient design enhances practical value:

The quick-release design simplifies the process of wheel installation, disassembly and daily maintenance, making the operation more efficient when repairing tires or replacing wheels, and significantly improving the convenience of use.
