Product Details

Built for Stronger MTB Performance

Designed for modern MTB six-bolt disc brake wheel builds, MT-065F/R combines a durable AL6061-T6 aluminum hub shell with a high-performance DT-36T/DT-54T ratchet system and Boost axle configuration. With a 15×110mm front and 12×148mm rear spacing, it provides an optimized balance of structural strength, engagement response, and wheel stiffness for demanding trail and all-mountain riding.

Full-Surface Ratchet Engagement

36T / 54T Ratchet System for Consistent Power Transfer

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.

Patented One-Piece Ratchet Architecture

Integrated Design for Higher Strength & Reduced Failure Risk

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.
