The ratchets for the Ratchet EXP System differ from the classic Ratchet System in that the loose ratchet has a seat for the straight spring. The integration of the ratchet and the threaded ring in the Ratchet EXP also allows for a smaller number of parts due to the use of a single spring. This also reduces the weight of the freehub system.

By integrating the drive side bearing into the threaded ring in the Ratchet EXP freehub system, the bearing distance can be increased, resulting in a 15% improvement in axle stiffness. To make the system as light as possible the axle is additionally machined in the middle.

The Ratchet EXP requires fewer single parts because of the integration of the ratchet and the threaded ring. Only one guided spring is used, which ensures precise engagement.

Ratchet EXP freehub bodies have no seal themselves, as this sits on the hub shell.

Freehub body options: Shimano 10/11-speed, Shimano MICRO SPLINE, SRAM XD
