Parellelogram type Suspension fork?
I came across this is a magazine the other day, it was some different type of suspension, i think they use it on motorcycles, and it was just a whole lot of metal, like a spring up the top of a rigid fork. It was called Parrellelogram suspension and I was wondering if anyone had heard of it before, and what is the point of it. Dont know if they still use it but I've never seen it on a bike before? Sorry no pics...
