LEGO Technic - Compact 8 Speed Sequential Gearbox

This gearbox is one of the most compact sequential gearboxes. It has in fact a 2 speed gearbox combined to a 4 speed gearbox. So there are 8 gears, but it&more compact. Thanks to this conception, the gearbox itself is more compact, and the shift system, using the rotary changeover catches of the Bugatti Chiron is also pretty compact. ____________________________________________________________
