Someone should tell those guys, that Stock trials bikes often have the freewheel at the cranks, so when you stop pedaling, the rear wheel is still engaged. If you can get your head around that concept, it kinda makes it look like the DaViinci people didn't do their homework ( or dismissed the idea for some reason I haven't considered ). That sounds like a much neater solution to me......although, you'd need both otherwise.........oh geez, what a mindfück.
