Professional

The wheels Professional (Fox, Panther, Mustang, Leopard) is the traditional series of Roll-Line© wheels which represents secure grip on any occasion and on any type of surface.

Given their characteristics, these wheels have been equipped with a rigid hub which supports the polyurethane tread.
The rounded finish allows for use in competitions with a minimal adjustment time.
It is possible to combine these wheels with the Devil wheels for a perfect balance between grip and smoothness.
Available in four hardnesses (colors) and one diameter: 57mm.
Available in sets of 8 wheels (It is at the discretion of each reseller to sell units in smaller quantities).

NOTE: being made of polyurethane, the Professional series is graded with a Durometer Shore (hardness) scale that is different with respect to other wheels. However, it is possible, with a fair approximation, to create a correspondence shown in the following tabs.

Roll-Line does not sell directly to the public; to complete your purchase, please refer to an official reseller.

Diameter	57mm
Profile	24mm
Hardness	92 / 95 / 97 / 99 Shore A
Floor	See Table

Indications for use

Each wheel hardness has been designed to adapt to a type of surface based on smoothness or roughness.
In general:

The softer the wheel (or the lower the “Shore” hardness number), the greater the grip and the slightly lower the smoothness.
The harder the wheel, (or the greater the “Shore” hardness number), the greater the smoothness and slightly less grip.

The following table shows the type of surface suggested for each wheel hardness.

FOX 92	PANTHER 95	MUSTANG 97	LEOPARD 99
Very slippery surfaces	Slippery surfaces	Medium surfaces	Adherent surfaces

WARNING: Factors such as humidity, dust, etc. can affect the seal of the surfaces.
For this reason it is preferable to have a variety of different types of wheels depending on where the training and competitions take place.
Changing the wheels does not require an adjustment period, but it is necessary to ensure that the wheels have a similar state of wear with respect to one another when equipped. To determine how to mix different types of wheels, please see the appropriate guide.

For more info on how to change wheels, please watch the video tutorial.

Control and maintenance

It is advised to verify the condition of your equipment at every use.
In particular, it is advised to check:

the state of wear of the wheels
the secure closure of the lock nuts on the wheels
the proper roll of the bearings

It is advisable to periodically clean the wheels, taking care to:

remove the bearings
remove the dust with a rag
wash the wheels with water and a light, neutral soap
avoid harsh products such as alcohols, gasoline, etc.

Periodic replacement

It is recommended to substitute the wheels in a timely manner, to guarantee the optimal performance of the equipment.
Substitute the wheels once the edges are rounded to a cone-like shape, as indicated in the following graphic:

NOTE
Possible natural color variation in polyurethane wheels, including but not limited to “yellowing,” has no effect on the quality, use, or performance of the wheels.
