BONES™ X-Formula XF Sidecuts 53mm x 31mm 99A V5 – Tech Power, Pro-Level Precision
Dial in your setup with the BONES™ X-Formula XF Sidecuts 53mm 99A – the perfect wheel for skaters who want to skate fast, slide clean, and stay in full control. Built with BONES' revolutionary X-Formula (XF) urethane, these wheels bring the speed and response of a hard wheel, with just enough rebound to tame rough terrain and crusty spots.
At 99A, they’re made for technical street skating, skateparks, and smooth concrete. The 53mm diameter offers quick acceleration and a lower center of gravity, ideal for fast flips, manuals, and locked-in ledge tricks. The V5 Sidecut shapecuts down on drag, reduces weight, and keeps you moving clean from setup to land.
