Has anyone had problems with their cup holder falling off while riding? It was installed at spyderfest in April/May. It started by moving side to side and my water bottle almost fell out a couple of times. Now the whole cup holder has fallen off twice. This last time there was a truck pulling their travel trailer, they were thank goodness far enough back that they had time to slow a little and this really nice stainless cup holder rolled to the side of the road. I just can not re-attach this without the worries of it coming off again. I guess I'm out $50.00, my camelback water cup has some dents but is still useable. Not sure if these photos show all the wonderful dents and scrapes.10547655_10154412113030323_8130985581511601084_n.jpg10518986_10154412113035323_326982750566985758_n.jpg Checked it and made sure the back nut was secure, not to loose and not super tight. Short of attaching it with duck tape I don't know what else to do...and no, duck tape, is not going on my bike.
