Seamless shift gearbox

Design of a simple cost effective seamless shift system: V-shift. V-shift converts conventional gearboxes into seamless shift transmissions. The concept is based on a twin drum system, but everything cleverly integrated into a single drum. This means by exchanging the conventional drum for the V-shift drum, a seamless shift transmission can be created. The system is completely mechanical and doesn’t require any complicated electronic assistance.
