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.
