Arbor Collective says their signature series is "team tested on mountain grades, neighborhood steeps, and city streets--using high performance urethanes, exclusive shapes, and fiberglass reinforced cores for enhances control, roll speed, and durability in all conditions."
The Signature Series features two styles: Axel Serrat's 'Spud' and Daniel MacDonald's 'Vice'.
According to Arbor, the 'Spud' wheel is "Axel's choice for big hills and long slides-- the Spud can hold it's own on both urban freeride spots and steep mountain roads. Our 82A Slicks Formula urethane offers effortless slides while the center of the Groovetube Core provides durability and control".
The 'Vice' wheel by Daniel is "a 69mm shape with an offset Groovetube Core that delivers the speed and stability needed for demanding terrain, while rounded lips and our 78A Nitro Formula urethane provides a forgiving slide for the freedom to leave thane lines anywhere and everywhere."
