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, harnessing, 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.
