Stand-alone quick shift module for seamless, clutchless, full-power upshifting.
The QS4 USB has user-adjustable gear dependent kill times allowing for optimal shifting in all gears. The kit comes complete with control unit, harness, shift switch and adapter rod. The software allows the user to set a signal to indicate to the rider precise shift points using the optional shift light (sold separately).
The QS4 USB is an updated version of the popular Bazzaz QS-4 Quick Shift. Customer feedback on the QS-4 led to the development of a new shift sensor for improved reliability, which now also includes an application-specific adapter rod for easy installation.
