This seems to work fairly well and doesn't shake or vibrate. You can get these assembled from eyeofmine.com or you can get the clamp from Bessy tools (XV5-100) and make one of these fairly easily. I didn't like the orange color of the original handles so out came the plasti-dip can (not spray). Plasti-dip made a huge difference in how well it grips the crossbar. I'm going to make my own bracket for the end of the clamp that is a little sleeker looking. I'm also looking for a slip knot cord to attach to the clamp in case of a crash. It grips really well but you just never know.
