Pretty disappointed in these baseball caps. I really wanted to like her - and at first I loved her. They're easy to install and look great on wheels, but the center pieces are *very* difficult to remove. Using the included takes broke the two middle pieces, making the entire set practically unusable. I really wish all of the centerpieces were solid, but they are cheap tin tape that is glued onto the centerpiece that scratches easily when removed. If you never plan to use your aerodynamic caps again, this product will do. But if, like me, you like to wear aero caps for a ride every once in a while, this product will almost certainly break on the first attempt to take it off.
