From Venezuela at Worlds onwards, Matter started an absolute domination of road, track and indoor racing. World champions, European champions and WIC marathon champions, they all have been depending on Matter wheels for years. Through the years Matter yellow has become an authority in inline racing. Go to any marathon in the World and you will see over 90% yellow.
It was Matter wheels to introduce the hollow core, EMT core, Image core, the concept of a convertible wheel etc. At Matter wheels they do not define a wheel to its hardness, they define it by footprint. Their World leading athletes test every wheel very thoroughly, and only the best of the best make it to the market place.
