G13 Inline Skate Wheels 8-pack

Advanced wheels designed for speed skating. Centred around the four-component TR3 system "Core improvement" and G13 Polyurethane. The Matter laboratories, alongside the Powerslide Matter racing team, are thoroughly confident that these wheels will dominate both track and road races for years to come.
The G13 PU provides excellent grip without ever sacrificing roll and delivers impressive acceleration out of the corners.
This 2015 wheel also incorporates S.E.R.T. technology, which stands for Stored Energy Ring Technology. The engineer behind the wheel, Neal Piper, explains this technology best:

"One of the most crucial structures within any inline racing wheel is the transition layer where a softer component joins a much harder mounting base. This is a vital energy management zone for a wheel.
At this pivotal hinge or pivot area, the force of the push and the 'stored rotational energy' within the deflected tyre must not be lost. When the transition or mounting layer between the PU tyre and harder plastic hub is constructed correctly, it enables a perfect balance between tyre flexibility and energy release throughout the entire wheel."
