and is it hard to change your wheels on your roller blades ?
The wheel color doesn't matter, but the softness of the polyurethane compound represented in a number like 86b or 74a does. The smaller the number, the softer the wheel for a smooth ride outdoors, but it will wear faster than harder compound wheels. I always liked Hyper wheels for outdoor blading. They held up well, lasted ages, except the front ones I drag to stop, and they ALL wear at angles, but these were light and smooth with their great hub designs. No, it is easy to change wheels, if you have the right tools. Allen wrenches, bearing puller/pusher, and thumbs. :)
