From 88 Wheel Co, the new 80mm Mitch Thompson Maverick Pro race formula focuses on pure speed and grip while the 86mm McFly Pro takes the existing McFly formula and turns it up a notch with lasting durability and speed....both 74a! Made in our new ultra durable race thane and poured in 74a, they feature the same chunk resilience and 99.9% bubble free pour as our original Mavericks and McFlys, and thanks to our precision bearing seat, they roll straight and true, giving you even wear and weight loading through turns.
