In Racecae Engineering magazine V14N2 (Feb 04) (no link on site found) the is a story on the ZeroShift cluchless gearbox system.

Originally starting as a way to make a shaft-drive bike Bill Martin came up with a way to shift under load without a break in power transmission. It is currently being tested in TVR Cerbera's and some other cars.

Let hope this make it back to bikes (and is light).
Success is how far you you bounce back up after being knocked down
