A sequential gear shift system for two-way operated speed change gear units of manually propelled vehicles. Mirrored, spaced-apart lever operators, are provided with increasing lever stroke ratio, and actuate sequentially with twin mirrored one-way multi-tooth rack-clutch mechanisms, that rapidly engage with a shift element and convert linear torque to rotate the shift element in diametrically opposite directions. The rack-clutch mechanisms may be disengaged from the shift element when returning to normal. The actuating may occur via independent hydraulic operation of an actuator. The actuator housing and load bearing axle of the speed change gear hub are selectively, releasably, and coaxially interconnected into a rigid gear system load bearing axle, and may be combined at any angle, and a shift direction is selectively reversible.
