It is important to replenish body fluids long before you become thirsty. The secret to this winning combination is to rotate your wheels. Wheel rotation will give you a better edge to skate on, thus improving your skating capability, as well as saving you money by prolonging the life of your skate wheels. Depending on the amount of skating you do, the surfaces you skate on, and your skating style, the inside edges will wear down over time. When the wear is noticeable, it may be time to rotate those wheels.
Wheel wear differently depending on the position of the skate.
When reattaching your wheels, be absolutely certain your wheels spin freely and the axle bolts are tight. You have lengthened the life of your wheels and you will get more push on every leg stroke. Happy and safe rolling.
