While fine pawls lack robustness, roller and sprag clutches are soundless and heavy. The patent-pending DOUBLE RATCHET SYSTEM provides fast engagement with the proven and robust ratchet technology as well as a unique stereo freehub sound - without breaking the scale.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eConventional ratchet freehub systems consist of two ratchet partners and all ratchet teeth engage simultaneously. As a result, the forces are distributed evenly over a large contact area, making the ratchet system of the utmost reliability.
