I spoke with the owner of Portapedal Bike and he mentioned that he had heard of a crossbar attachment for the M type Brompton handlebars. He is going to do some research on it, but I was wondering if anyone here has heard of such an item. It's an attachable bar that goes across the uprights of the M type handlebar. This allows for better placement of accessories like lights and cyclometers etc. If anybody knows anything about this, please post.
