Dahon Handlepost Upper Section 28.6mm Black.  Suitable for the adjustable Radius and Radius V Handleposts. As this product is factory matched (and Dahon handleposts have been made in many different factories) it may be necessary to file the hinge area slightly in order for it to fit   This cap is really made for the latest handleposts that have a catch on the cam lever. but it will also suit the earlier types that have a 28.6mm upper section.   Will also suit the fixed height types like Jetstream P/D 8   Black Supplied.
