When to Rotate Skate Wheels:
You will know it's time to rotate your skate wheels, when you see that one side of your wheels - usually the inside edge - is wearing down more quickly than the other. Another signal is when you can see that some of your wheels are noticeably larger than others, but if you can see this difference, you have probably waited too long.
After You Rotate Your Wheels:
Freshly rotated wheels can feel a bit strange when you skate on them and it can be difficult to keep your balance. This problem can be reduced by rotating your wheels frequently, and by rotating the largest wheels to the front and back positions. If you your wheels do feel strange after rotating, they will feel normal again after a few days of hard skating
1) Speed Wheels - Designed to grip the skating floor and allow you to gain traction while gaining speed.
2) Artistic/Dance Wheels - Designed to be hard wheels that are not "grippy" to allow for the dance style moves in skating.
3) Outdoor Wheels - These are softer wheels that are designed to be able to absorb the uneven terrain of outdoor skating surfaces (e.g. trails, sidewalks, boardwalks, roads).
4) Derby Wheels: The wheels are designed for the sport of Roller Derby. These allow the different positions in Derby to be able to stop quickly, go quickly, and go at fast speeds.
1) The Wheel Hardness is measured on the Shore scale:
Either on the D scale or the A scale
D scales are for harnesses of Plastic Compound Wheels
A scales are for harnesses of Urethane Compound Wheels
The lower the Number the softer the wheel, this provides more grip with a little less roll. The higher the number the harder the wheel this provides a little less grip with more roll.
2) The Wheel Diameter is measured in millimeters
55mm and 57mm are used for Freestyle skating, primarily. (the 55mm are based on a lowering of the center of gravity).
63mm are used for Dance Wheels, Derby and General Skating.
63mm are used for the LARGE Figure Circles
61mm and 62mm are used for Hockey and Speed (are based on just a small lowering of the center of gravity).
60mm are used for LOOPS.
Small wheels will provide the maneuverability needed for aggressive skating, figure skating, roller dancing, and hockey.
A larger wheel will provide the smooth ride and faster speed that is desirable for fitness and speed skating, however accelerating from a stop to full speed will require more effort on very large wheels.
Before you purchase new wheels for your skates, make sure the wheel size you are buying will fit on your skates and frames.
And remember when buying wheels bearings do not come with your new wheels.
What are hubs?
Soft wheels below 84A need a hub to reinforce the bearing seat in the wheel. Under normal conditions, an 84A wheel will hold the bearings, but not under extreme conditions. Hubs are used on harder wheels only to lower the weight of larger wheels. Usually nylon or aluminum hubs are much lighter than the urethane they replace. Metal hubs are preferred over nylon hubs to produce a much stiffer wheel and provide a better feel to the top end skaters. Nylon hubs tend to flex while skating.
Do not worry about the holes, these bubbles do not affect the performance of the wheels and in fact, they prove that the material is truly POLY BD which enhances the performance of the wheels on skating surfaces.
1) Attach the correct socket wrench (usually 11/16 inch) to the ratchet body of your wrench.
2) Fit the wrench on to the bolt and move the handle right and then left, until the nut reaches the appropriate tightness.
3) Feel the nut with your fingers to test the tightness. Loosen or tighten as needed. A medium tightness is recommended.
4) Repeat on the final three nuts.
