I recently became the owner of a wonderful Airnimal Joey with Ergon GP3 handlebars. It's a wonderful bike but I would like to install a bar end mirror. I used one on another bike and it was a real benefit. I am told by some that putting one those handlebars is possible, but others say no. I tried a couple of different mirrors that are attached to the bars, but there is very little room if I am to have more than one place for my hands - one of the reason for the new bike. Any advice would be very much appreciated. Thanks
