The SDS (switch drive system) is something we developed a couple of years ago, and has gone a little bit under the radar. As the name suggests the system allows the hub to be flipped from right side, to left side drive.

The system works thanks to a unique design allowing the ratchet ring to be totally removed from the hub shell. It can then be put back into the hub with the teeth pointing in the opposite direction, giving the opposite drive. The design hasn’t ever stood still, as we are always looking to improve and refine the design, for 2013 we modified the outer profile of the ratchet ring to a wavy spline pattern that really improves the strength of the ratchet and makes assembly into the hub shell easier.
