Shifting Technology
PowerShift VST shifting is accomplished using an electronic shift system. Electronic shift systems have recently been developed for derailleur-based transmissions. These systems are very expensive and only work with select gearsets. A relatively inexpensive electronic shift system has been developed and successfully applied to the PVST System. This electronic system works universally with all PVST Systems and Configurations.
Why PowerShift VST?
Because gear changes are accomplished with the chain/belt conveyance remaining in a constant plane, and by simply lifting or lowering the conveyance from one pin row to the next, it is possible to maintain the application of power during the shifting process.
