BONES™ X-Formula XF Sidecuts 54mm x 30mm 99A V5 – Fast Lines, Smooth Control

Looking for that perfect middle ground between speed and grip? The BONES™ X-Formula XF Sidecuts 54mm 99A are the answer. Made with BONES’ cutting-edge X-Formula (XF) urethane, these wheels are all about high performance across a variety of surfaces — from smooth park transitions to rough urban streets.

The 99A durometer hits the sweet spot: slightly softer than your typical street wheel for added grip and shock absorption, but still fast, hard, and built to slide when you need it. Paired with the V5 Sidecut shape, you’ll feel less drag on grinds, sharper flicks, and better control through every turn and trick.

Why skaters choose the XF 99A Sidecuts:

• X-Formula 99A urethane – fast-rolling with just the right amount of grip

• Sidecut V5 shape – optimized for tech control and clean slides

• 54mm x 30mm sizing – ideal for street and park versatility

• Soft edge design – reduces hang-ups on ledges and rails

• Resists flatspots – ride longer, harder, and smoother

If you're skating a mix of surfaces or just want a smoother ride without giving up slide and speed, the XF Sidecut 99A is your go-to.

Refined feel, serious tech – ride BONES X-Formula 99A.
