Compared with conventional pawl systems, the larger contact area distributes drivetrain loads more evenly, reducing localized stress while improving durability, engagement stability, and pedaling efficiency under demanding riding conditions.
ARC's patented one-piece ratchet design integrates the engagement structure into a single precision-engineered component. The system increases structural rigidity, reduces overall weight, and improves machining accuracy. The simplified construction also enhances long-term reliability while making assembly and maintenance more efficient.

Engineered with a lightweight aluminum-carbon composite hub shell and high-strength aerospace-grade aluminum components to meet the demands of modern road rim brake wheel builds.
✓ High-Strength Aerospace-Grade 7075 Aluminum Alloy Axle & Freehub Body
The axle, freehub body, and end caps are manufactured from aerospace-grade AL7075 aluminum alloy, enhancing structural stiffness and durability while maintaining a lightweight construction.
✓ 20H / 24H Straight-Pull Configuration
The 20-hole front and 24-hole rear configuration supports 1:1 and 2:1 spoke layouts, providing flexible options for optimizing spoke tension distribution, wheel stiffness, and overall wheel balance.
✓ Lightweight 358.3g±5g Hubset Construction
A carefully optimized aluminum-carbon composite structure keeps the complete hubset weight to just 358.3g±5g, reducing rotational mass while maintaining the structural strength and reliability required for responsive road performance.
✓ Multiple Freehub Standards Available
HG and XDR freehub options support different road drivetrain configurations, providing flexible compatibility for a wide range of modern road wheelset applications.
✓ Road Rim Brake & Quick-Release Compatibility
Designed for 100mm front and 130mm rear spacing, with the QR019 road quick-release system, providing compatibility with traditional road rim brake wheel builds.
