This road bike straight-pull disc brake hub is a core component designed for riders pursuing lightweight performance. Crafted from 6061+7075 aluminum alloy composite, it weighs as low as 269g, striking a balance between lightness and structural rigidity. The straight-pull spoke design, combined with a 12*100/12*142mm through-axle structure, enhances force transmission efficiency and wheel stability while enabling easy assembly and disassembly. Featuring 24/24 holes, it accommodates various spoke patterns, with optional steel ball or ceramic bearings to suit different needs. Compatible with multiple freehub bodies (including Shimano HG/MSR/N3W/XD), it works seamlessly with mainstream shifting systems. Paired with a disc brake system for stable braking, it provides efficient and safe core support for road cycling.

Product Features and Advantages

Weighing as low as 269g, it is crafted from a composite of 6061+7075 aluminum alloys. While achieving extreme lightness, it balances structural rigidity through the high strength of 7075 aluminum and the corrosion resistance of 6061. This effectively reduces wheel inertia, enhances acceleration and climbing efficiency, and withstands stress during high-speed riding.

Structural Design:

The straight-pull spoke design minimizes force transmission loss, boosts wheel rigidity and wind resistance performance, and improves power output efficiency. The 12*100/12*142mm through-axle structure not only offers higher strength to ensure stability during high-speed and intense maneuvering but also simplifies wheel assembly and disassembly, compatible with mainstream road bike specifications.

Flexible Adaptability:

The 24/24 hole count balances strength and lightness, compatible with various spoke lacing patterns. It provides two options: steel ball bearings (cost-effective, suitable for daily use) and ceramic bearings (low friction, high durability, ideal for those pursuing ultra-smooth performance). Supporting multiple freehub bodies such as Shimano HG/MSR/N3W/XD, it widely adapts to different shifting systems, meeting diverse needs from training to competitions.

Brake Design for Safety:

Integrated with a disc brake system, it delivers stable and powerful braking performance even in complex road conditions like dry or wet surfaces. Combined with the high-rigidity wheel design, it builds a solid safety barrier for road cycling.

Application Areas

Application areas for the RH-SS260-DB rim brake hubs:

• Daily road commuting：

The lightweight design (269g) and cost-effective steel ball bearing option reduce riding burden, making it ideal for short to medium-distance daily commutes, balancing efficiency and durability.

• Road training and long-distance riding:

The straight-pull design enhances force transmission efficiency, while the through-axle structure boosts wheel stability. Combined with the reliable braking performance of the disc brake system on complex road conditions (such as wet roads after rain), it meets the demands for endurance and safety during training.

• Road racing and speed pursuit：

The ultra-light weight reduces wheel inertia, and the low-friction ceramic bearings improve rotational smoothness. Paired with the multi-freehub design compatible with mainstream shifting systems, it helps achieve efficient acceleration and precise shifting in competitions, suitable for advanced riders pursuing results.

• Leisure road riding：

The flexible compatibility with various spoke lacing patterns (24/24 holes) and easy wheel assembly/disassembly (through-axle design) allow for adjusting wheel styles according to personal preferences, while the disc brake system ensures braking safety during leisure rides.
