Arbor Rally Cork Top Mini Crusier Skateboard. Part of The Mini Collection. The new Rally is a cork-topped version of the Bat Tail. Like the Bat Tail this skate is ideal for around town surf-inspired skating. Complete includes: Arbor 65mm, 78a durometer Street Series wheels, ABEC 5 bearings, and 9” Gullwing Charger trucks. Cork is the original renewable material. It has been used as a valuable resource for thousands of years. Cork is a bark that is harvested every nine years off cork oak trees without harming the three. Cork is an excellent natural insulator. It dampens road vibration, while providing grip for barefoot skating. All Arbor skateboards are produced using a water-based sanding sealer and final finish to avoid polluting the air we breathe, especially when skating.
