The Spitfire Formula Four Conical 99a Wheels are engineered for riders who demand a lightweight, highly responsive wheel without sacrificing the stability of a wider riding surface. Featuring a “true performance” conical shape, these wheels are hand-cut with a distinct tapered sidewall that reduces bulk while allowing for a secure lock-in on rails and ledges.

Built with Spitfire’s industry-leading Formula Four (F4) urethane, these wheels provide unmatched resistance to flatspots and a “smooth anti-stick slide” that won’t skip or catch mid-trick. The 99a durometer is the preferred choice for all-around performance, offering high speed on smooth concrete and park floors while providing enough vibration dampening to handle crusty street spots. Because the conical shape places more urethane toward the edge of the wheel, it offers a wider contact patch than the standard Classic shape, giving you more control and grip when you need it most.
