If you looked at them side by side you would be astounded how similar they are and if you were a machinist looking to design a better freehub this would be the way it would look.

I have seen such a nice variety of Arvon hubs... I run several wheelsets on my own bikes and have built a lot of wheels around them (usually touring and tandem) but also have some time trial hubs that are pure sex to look at.

Arvon provided the 1984 Olympic cycling team with their hubs, the carbon wheels they were mated to were also produced here by Dynamic Composites and the owner is my neighbour... I would love to get my hands on one of those wheelsets.
