The new Stamina cranks are out finest and the most inventive cranks yet. The arms, which are our strongest so far are made from a self-created model of heat-treated 4130 CrMo as well as the axles which are 19 mm CrMo ultra hollow. The PS cranks feature a new CrMo bolt with a spline for a better grasp. This model is designed to take the strain, stress and power of today’s most fierce riders.
