Well, here's the problem. I just bought new paddles, Extremes 20x10x10, and I was all excited to put them on but... my old ones refuse to come OFF!!!! These are the options I've tried: 1. Of course, removed the wheel locks. (Not a complete moron) 2. Smacking them with a mallet. 3. Used a piece of wood and nocked on the back of the wheel to try to shake things up. Any other suggestions would be great! By the way this is a girl so be gentle with the jokes!
