This road bike hub is a high-performance component designed to meet the diverse needs of cyclists. It boasts broad compatibility, supporting HG, XDR, MSR, and N3W freehubs, which means it can work seamlessly with Shimano and SRAM cassettes. The standard 12×100mm (front) and 12×142mm (rear) thru-axles ensure it fits most disc road frames, making upgrades a breeze.

In terms of construction, it combines a 6061 aluminum body, known for its corrosion resistance, with 7075 high-tensile components, striking an excellent balance between lightweight and strength. Weighing just 313g, it reduces rotational inertia, making climbs easier while being able to handle tough riding conditions.

Performance is optimized with a straight-pull design that enables efficient power transfer. Cyclists can choose between steel ball bearings, ideal for durable daily use, and ceramic bearings, which offer low friction for racing. Additionally, the thru-axle paired with disc brakes ensures stable and reliable stopping power.

Maintenance is made easy thanks to its precision-machined aluminum that enhances durability, and a user-friendly design that allows for simple cleaning and lubrication without the need for special tools, keeping the hub in top working condition.

Product Features and Advantages

Supports mainstream freehub specifications such as HG, XDR, MSR, and N3W, adapting to different speed cassettes of brands like Shimano and SRAM . There's no need to replace the hub due to differences in shifting systems, which greatly improves the product's versatility and meets diverse matching needs from daily riding to professional competitions.

Standard Thru-axle Sizes:

Adopts standard thru-axle designs of 12×100mm (front wheel) and 12×142mm (rear wheel) . It matches most disc brake road bike frame specifications on the market, enabling easy installation. There's no need for additional frame modifications when upgrading wheel sets, reducing the adaptation threshold.

Composite Aluminum Alloy Material:

The main body is made of 6061 aluminum alloy (corrosion-resistant, easy to process), and key components use 7075 high-strength aluminum alloy (high tensile strength) . While ensuring overall structural rigidity, the weight is controlled at 313g, achieving a balance between lightweight and durability, reducing wheel set rotational inertia, improving riding efficiency, and being particularly suitable for climbing and high-speed sprints.

Straight-pull Spoke Design:

Spokes extend directly from the center of the hub to the rim, reducing stress concentration. Power transmission is more direct and efficient, with the wheel set responding sensitively when exerting force, reducing energy loss. It also simplifies the wheel set lacing and maintenance process, facilitating daily upkeep.

Dual Bearing Options:

Offers two choices: steel ball bearings and ceramic bearings . Steel ball bearings are cost-effective and highly durable, suitable for daily commuting and long-distance riding; ceramic bearings have a low friction coefficient and rotate smoothly, which can reduce power loss, meet the performance requirements of competition levels, and cater to different users' budgets and usage scenarios.

Disc Brake + Thru-axle Combination:

Adapts to disc brake systems and is paired with a thru-axle design . The thru-axle provides higher rigidity, effectively reducing deformation during braking, ensuring stable transmission of braking force, making braking more reliable during rainy days or high-speed riding, and significantly improving riding safety.

Precision Machining and Easy Maintenance Structure:

Aluminum alloy components undergo precision machining, and the structural design is easy to disassemble. It enhances corrosion resistance and prolongs service life; daily cleaning and lubrication do not require professional tools, allowing users to maintain it by themselves, reducing usage costs and keeping the hub operating efficiently for a long time.

Application Areas

Application areas for the RH-SS330-DB rim brake hubs:

• Daily Commuting and Leisure Riding:

With its durable steel ball bearings and corrosion-resistant 6061 aluminum alloy body, the hub can withstand the wear and tear of daily use, including exposure to wind, rain, and dust. The easy maintenance structure allows commuters to keep it in good condition with simple cleaning and lubrication, ensuring reliable performance for everyday trips to work, school, or casual rides around the neighborhood.

• Long-Distance Road Cycling:

The balance between lightweight (313g) and durability makes it ideal for long-distance rides. The efficient power transmission from the straight-pull spoke design reduces energy loss, helping riders conserve strength during extended journeys. Additionally, the stable braking performance of the disc brake and thru-axle combination provides safety and confidence, even when covering hundreds of kilometers on various road surfaces.

• Bike Upgrades and Custom Builds:

Thanks to its multi-spec freehub compatibility and standard thru-axle sizes, the hub is a perfect choice for cyclists looking to upgrade their existing wheel sets or build custom bikes. It can easily match with various frames, cassettes, and other components, offering flexibility and versatility in creating a personalized ride that meets specific performance and style preferences.
