Product Description
FLUIDO 45D, 47D, 49D, & 53D – 57mm Professional Injection FreeStyle Wheels
Hardness: Fuchia=45D, Blue=47D, Grey=49D, & Cappuccino=53D
Diameter: 57mm
Compound: Mixed Compound Elastomeric Formula
The Roll-Line FLUIDO 57mm Professional FreeStyle Wheels represent the start of a whole new class of Wheels. This very high quality wheel, is designed to be used on many types of skating surfaces including standard wood floors coated with plastic or poly urethane, but also unusual surfaces like, tile type basketball and volleyball courts, tennis courts (Indoor or outdoor), and concrete or terrazzo surfaces that are more common around the World. The FLUIDO 57mm Professional FreeStyle Wheels are used a great deal internationally, where there are few indoor skating centers like there are here in the USA.
The Roll-Line FLUIDO 57mm Professional FreeStyle Wheels utilize a stiff Delrin hub which is Strong, Light, and with Close Tolerances for Roundness, Trueness, and for the Cage where the Bearings and Spacers are mounted. The Roll-Line Tread is an Injection Molded secret Mix of Elastomeric Materials Formula, which provides strong Grip, while providing great ROLL. The Roll-Line FLUIDO 57mm Professional FreeStyle Wheels have a little more feeling of spring or bounce as they have a higher REBOUND than most other Roll-Line Thermo-Plastiche and Urethane wheels (except the Helium Wheels). This REBOUND creates a feeling of smoothness to the roll on the floor. The Roll-Line FLUIDO 57mm Professional FreeStyle Wheels has a small profile width.
The tread color identifies which hardness the wheels are.
45D = Fuchsia
47D = Blue
49D = Grey
53D = Cappuccino

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. The Shore “D” scale is used for Rubber and Plastics, while the Shore “A” scale is used for Urethane.
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.
