29. How do I read the code on the Matter Race wheels?
The code on the wheels contains a mix of letters and numbers giving various informations about the
wheel.
Let´s take an example: F184rsc
F = Footprint
F0/F1 /F2 /F3/F4 = hardness of wheel or footprint
The number behind the footprint is the wheel size
Example: F184 = 84mm wheel
The last letter indicates the special use of the wheel
r = road t = track i = indoor sc = solid core
Going back to the example above:
We have an 84mm road wheel with solid core and a hardness of footprint 1 (hard).
Quite simple, isn´t it?
30. What´s the technology behind Matter Wheels?
One important feature is the core of the wheel. Matter offers a unique hollow core technology. One
advantage is the reduction of the overall weight of the wheel. Another advantage of the core
construction is the aerodynamic. Bigger wheels often have problems with air turbulences which
results in a commotion role of the wheel. The closed core of the Matter wheels prevents the wheel
from air turbulences. Some companies try to solve the problem with carbon or composite shields for
the hub, but gain more weight again..
The extreme grip is another advantage of Matter wheels. The unique PU compounds allowe the
athlete to skate with full power keeping the maximum speed. Powerfull sprints, extreme curves or
slippery floors are no problem with Matter wheels. Get a grip!
31. What is Ultrasonic Welding?
Ultrasonic welding is the method of joining two parts by converting electrical energy into heat
energy by high frequency mechanical vibration and is suitable for plastics or metals. One part of the
assembly is set in motion in order to cause intense friction between the two pieces, one of which
remains held in place. This movement is provided by a vibrating component called a sonotrode
which is applied at right angles to the surface of the part to be welded.
