Formula Four Lock Ins 101A 55 mm (white)

Spitfire Wheels presents the Formula Four Lock-Ins 101A Wheels!
Spitfire brings the legendary Formula Four urethane mixture to the Lock-Ins wheel shape. There's a reason the saying goes \"Burn Four-Ever\"! The Formula Four urethane is considered the longest-lasting urethane in skateboarding. This wheel has a hard and fast 101A durometer and the Lock-Ins shape is flat on the inside of the wheel so that they easily lock in to grinds on ledges and coping. The outside of the wheel has a conical shape.
The Formula Four Lock-Ins 101A Wheels have a natural, gum-colored urethane and a sick \"Lock-Ins\" graphic on one side and text on the other side. Choose your desired size and get ready to light up the underground.
