Review on Minoura BH100S Bottle Cage Holder: Securely Holds Bottles (22-29mm) by Michael Crossman

Minoura engineers came up with a clip. It is fully adjustable to a variety of handlebar sizes. It's not really a clamp and release mechanism, because to hold a full water bottle, you first have to bring it closer, clamp, and then tighten the hex nut. Then he doesn't move. But no other clamp I've seen was as well designed. Minoura also makes a staggered version. So if you want the bottle to fit in the middle of the handlebar, look for that. Same price, same clamp style.
