Bones X-Formula Double Locks V7 54mm X99 Skateboard Wheels — Black (Set of 4)

Bones X-Formula (XF) is the brand's breakthrough urethane that does what used to be a contradiction: it rolls over rough terrain like a soft wheel while sliding with the precision of a hard one. A super-high-rebound formula makes it fast and smooth on any surface, absorbing vibration and softening impacts so it's easier on your body over a long day of skating — and it grips when you need control, breaks loose when you call for it.

This set runs the V7 Double Locks shape at 54mm with a wider 34mm profile. The straighter edge and tighter profile are built for lock-in stability — dialed for locking into grinds and holding your position on ledges and rails — while the added width gives you more control through slides. The firmer X99 durometer keeps it fast and slidey, and the clean all-black colorway looks sharp on any setup. Center-set hub lets you rotate the wheels for even wear. Sold as a set of four.
