Standard handlebar clasp for Q-Mount PRO/MAX

Gave this 4 stars vs. five because of the fact I had to order this part in the first place. I received a QMount as a gift last year - and it was working fine - five stars. Then one of the two plastic shims required to fit the handlebar clamp to my bike's handlebar worked itself out and fell off, rendering the clamp useless. I had to purchase an entire handlebar clamp just to replace one of the two shims. This year's shim design is much better - it's a solid rubber ring vs. two hard pieces of plastic. I hope this design change solves the problem, it seems to be a much better design.
