G13 Inline Skate Wheels 8-pack

Advanced wheels designed for speed skating. Centred around the four-part TR3 system "Core improvement" and G13 Polyurethane. Matter laboratories, in conjunction with the Powerslide Matter racing team, are exceedingly confident that these wheels will prevail in both track and road racing for years.
The G13 PU provides excellent grip while never compromising on roll and offering great pop when taking turns.
This 2015 wheel also incorporates S.E.R.T. technology, an acronym for Stored Energy Ring Technology. Neal Piper, the engineer who created this wheel, explains the technology best:

"A crucial feature of any inline racing wheel is the transition layer where a softer structure meets a much harder mounting base. This is a very critical energy management zone for a wheel.
At this pivotal or hinge point, the power of the push and the “stored rotational energy” within the deflected tyre cannot be lost. If a transition or mounting layer between the PU tyre and the harder plastic hub is constructed correctly, it offers a perfect balance between tyre flexibility and energy release throughout the entire wheel."
