I have one of
these and like it a lot. Sorry, no pics of it on my bike. It's mounted on my commuter and has been steady as a rock all summer. I also have a slightly
less secure holder, and use it on a couple of different bikes. It's handy because it has a little pocket for my keys, card and glasses. I very highly recommend the first, and really only mention the second because it's easier to switch from bike to bike.
