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.

MAGNUM 49	MAGNUM 53	MAGNUM 57	MAGNUM 60
Slippery surfaces	Medium surfaces	Adherent surfaces	Rough surfaces

ATTENZIONE: fattori quali umidità, polvere etc. possono influire sulla tenuta delle superfici.
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:
