Hard to turn the cleat to unclip or hard to turn the cleat FAR ENOUGH? If you are using a cleats/pedal combination with a high amount of float, it can be hard to get the cleat far enough around to engage the unclipping mechanism. I use the gray Look Keo cleats and have no problem, but I can't readily unclip when I try the red cleats with twice as much float. So is it the tension or the float causing the problem? At the loosest setting, the tension should not be an issue.
