The Giotto 50D, 54D, 58D, and 61D X 60mm Professional Figure Wheels are exactly the same as the Giotto 63mm Wheels, but offer a little lower Center of Gravity to be able to dig into the edges in the Loops and provide a great range of Grip and lot’s of Roll and are the World Standard for Loops by which all other Figure wheels are compared. The Giotto Professional Figure Wheels are primarily used for the Loop Circles. Most of the World level Figure competitors use the 60mm for the Loops Circles and use combinations of hardnesses of the Giotto Professional Loop Figure Wheel to achieve the best Skating result. Roll-Line has developed this wheel giving it properties that provide great roll with just the right amount of grip for figures. Compulsory Figures are high precision exercises. The feet transmit the impulses to the skating boot and thus to the steering (for the direction) and finally to the wheel (for contact with the skating surface). The Roll-Line Giotto Professional Figure Wheels (50D, 54D, 58D, and 61D) are a Lo-Profile wheel with exceptional Roll characteristics with extremely Close Tolerances for Roundness, Trueness, and for the Cage where the Bearings and Spacers are mounted. The Roll-Line Giotto Professional Figure Wheels are a MonoCompound Elastomeric ThermoPlastiche wheel, which is produced utilizing an injection system and is Silver Chromed. The 50D, 54D, 58D, and 61D provide a great varying range of grip in the wheel material and is for a skating surfaces with a range of grip. For most Skaters, a hardness one (1) level softer than is used for the Long Circles, is what is generally used for Loops, including the Push Wheels (1 Step DOWN).
The wheel color identifies which hardness the wheel is.
In the USA, most skaters use the 61D, while stepping down to the 54D or sometimes the 58D for the inside toe wheels as additional Push Wheels.
The softer the wheel, or lower Shore “D” hardness number, the more the grip and slightly less roll. The harder the wheel, or higher Shore “D” number, the more the roll, with slightly less grip.
It is almost always recommended to use spacers in the wheels, when using standard 7mm bearings. Long ago, before the use of Lock Nuts (the nuts that have the Nylon Plastic inserts) to hold the wheels on the axles, Jam Nuts were used, but when the spacer was not as wide as the web of the wheel, or the wheel was not machined accurately, the bearings would lock up, the nut had to be tight, and could not be “backed-off”. This method, of locking the Axle Nut down, did promote proper bearing alignment and did increase the diameter of the axle from 7mm to approximately 14mm, because everything was locked down, which also saved the problems of bent axles. Today we do use Lock Nuts. It is still very advisable to lock everything down (especially for FreeStyle, Jam, and Roller Derby Skaters). Roll-Line does provide Spacers for Roll-Line Wheels with each pair of Frames or they can be purchased separately. Properly locking the Wheels down when using standard bearing types, will also promote longer bearing life.
The Roll-Line 7mm SpeedRace & SpeedMax Bearings , are specifically made for very High Level Competitive FreeStyle Roller Skating and are a very Durable Bearing with lots of ROLL. The SpeedRace & SpeedMax Bearings are Free Rolling with minimal Radial Play which promotes and very evenly distributes the load across the 7 or 8 (of the SpeedMax) balls for optimal Roll and a good amount of Axial Play or Thrust, which is the side movement of the inner race in relation to the outer race. This movement is very important because when Skaters push, we always put side load on the skate to get power in the push or stroke. If the Bearing does not allow for this, it will bind and LOOSE operating speed or ROLL. These provisions in the Race Curvature and Contact Angle allow the Roll-Line SpeedRace & SpeedMax Bearings to ROLL very freely
The Roll-Line SpeedRace Bearings have 7 balls and a rubber sealant Shield and the SpeedMax have 8 balls and a metal Shield and are ONLY available for 7mm Axles. The Roll-Line SpeedRace & SpeedMax Bearings are skated on by most of the World level FreeStyle Skaters and Champions.
The Giotto Professional Figure Wheels may be purchased in sets of 8, as normal, but sets of 2 wheels are also available for any of the 4 hardnesses. Two (2) Push Wheels, will be priced at (25%) of the price of a full set of 8.
