The TiLT Formula Deck is the successor of TiLT's original deck, the Theory. The Formula features a cut out on the bottom of the deck which reduces weight, and is better than a completely flat bottom because it produces less friction. Less friction means smoother grinds! The updated welded dropouts will also make for extremely smooth grinds. The Formula comes in 5 different sizes, and Will decided to choose the 6.5" wide by 22.8" long for his signature deck. This size is going to be ideal for riders who want foot and grind space. Will's signature deck is a limited one time release; once they're gone, they're gone forever!
