THYS 222 RR version

11 February 2014

The RR version of the 222 has the THYS design rear hub with roller ramp freewheel clutch. This -very expensive- clutch ensures a direct grip on the rear wheel in the beginning of the stroke. The shifting system has improved but is not perfect. Diameter of the snek is limited to 120 mm. Only tall people can shift to the lowest gear while riding.
