BONES X-Formula V5 Sidecut – Kowalski Against the Grain, 54mm, 99A

The BONES X-Formula V5 Sidecut Kowalski Against the Grain wheels are built with Bones’ groundbreaking X-Formula™ — a decade in the making and fine-tuned for peak performance. XF rolls over rough terrain like a softer wheel but slides like a harder wheel, giving you the best of both worlds.

At 54mm with a 99A durometer, these wheels deliver smoother, faster rides on any surface thanks to superior vibration absorption and impact damping. They soften landings, reduce body fatigue, and extend your skating sessions, all while offering precision control and reliable slide performance.

With the V5 Sidecut shape for extra control on ledges, rails, and transitions, these wheels are more than just gear — they’re a game-changer.
