Giotto

The Giotto wheels are designed for competition-level roller skating, and are the most popular Roll-Line© wheels.

Monocoque wheels produced via injection of a mix of thermoplastic polymer materials.
Provide an optimal compromise between grip and roll, thanks to their tapered profile.
The rounded finish allows for use in competitions with a minimal adjustment time.
Brilliant and elegant chrome coverage.
Available in five hardnesses (colors) and two diameters: 57mm and 55mm
Available in sets of 8 wheels (It is at the discretion of each reseller to sell units in smaller quantities).

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

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.

Each color corresponds to a specific hardness (as shown in the table): 47 light blue, 49 grey, 53 beige, 57 cream, 60 white.

NOTICE:Factors such as humidity, dust, etc., can negatively influence the grip of the wheels on the skating surface.
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 sliding 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:
