Zero

In-line

Produced with an exclusive Roll-Line© mix of materials, the Zero wheels are the perfect partner for the Linea frame.

Their rounded profile renders them perfect for inline artistic skating, as opposed to other, less-specific wheels.
Available in two hardnesses: 82 (white) and 86 (beige).
Four diameters to match the different measurements of the frames available: 64mm for frames sized 7 1⁄4 - 8; 68mm for frames sized 8 1⁄2 - 9; 72mm for frames sized 9 1⁄4; and 76mm for frames sized 9 3⁄4 - 10 - 10 1⁄4 - 10 3⁄4 - 11 1⁄4.
Available in sets of 6 wheels (It is at the discretion of each reseller to sell units in smaller quantities).
Product sold separately from the frame.

NOTE: Being made of polyurethane, the Zero wheels are graded with the Shore scale A.

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.

Zero 82

Zero 86

Slippery surfaces in general, preferably wood or polished parquet. Indoors only.

Medium slippery surfaces, smooth or quartz concrete. Moderate outdoor use. Avoid very rough (asphalt) or uneven (tile) surfaces.

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.

Each color corresponds to a specific hardness (as shown in the table): 82 white bush, 86 beige bush.

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 correct closure of the nuts and spring washers
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:

A. New wheel
B. Wheel worn unevenly; must be rotated
C. Wheel worn unevenly and excessively; to be replaced
D. Wheel evenly worn but significantly reduced in diameter; to be replaced.
