The Cymatics Team Wave Wheels were made to be used together in a flat mixed-duro setup with the Adaptive 60 92A version on the outside and the Heavy Hitter 95A on the inside.  But that's not to say you can't roll how you want to roll.
 
Cymatics are made in the USA and come in packs of four. The Cymatics Heavy Hitter 95A Wheels are intended for rough street spots, as well as harsh, hot weather (anywhere that shreds soft wheels).  They are hard but offer excellent rebound and grip qualities for a smooth ride. The Adaptive 60mm/92A Wheels offer a perfect combination of durability, speed, and grip on a variety of surfaces. Both versions have a round profile for smooth, controlled rolling.
