Reet guys, I have at the moment some lock on grips holding some makeshift extenders in. Nae too safe to be honest, However, im looking at getting some dowel for extending my Monty bars..... My question is....does anyone know the diameter of dowel that would fit best? or someone who might know the internal diameter of the bars please. I did the search and read the topic that comes up fourth on the list. Just want to get a size cheers
