Bumbee P. CA349 (RATCHET) launched a new zero-time planar tooth ratchet for the ratchet body drive structure. During the 360-degree driving process, the zero-time planar tooth ratchet body has two parallel tooth surfaces (48 teeth) to achieve a zero-gap occlusal action at the same time. The complete occlusal and propulsion allow the driving performance to be more directly output. In addition, the zero-time planar tooth-type occlusal structure is more durable than traditional pawls.

DESCRIPTION:

- Zero-time planar tooth ratchet freehub, driving performance to be more directly output.

- The brake side features a milled groove drainage design to enhance braking performance.

- Lightweight 349 carbon fiber wheelset.

- High-precision smooth and wear-resistant ceramic bearing.

- Exclusive drilling angles for hubs and spoke holes. (reduce the corner angle )

- All hand-built by wheel-building technicians.

- Hubsmith high Tensile and high-pressure rim tape.
