Sure-Grip Zombie Wheels are made in the USA & feature anodized aluminum hubs for maximum durability & precise feel while maintaining rock solid stability. The solid hub allows the Zombie's unique urethane compound to deliver all of your power to the floor! Three size profiles - Low, Mid, & Max - offer varying degrees of speed, grip, stability, & lateral movement. Heads up! These hubs are precision-machined, which allows bearings to slide perfectly in...and also slide perfectly out. This is a non-issue, we promise! Simply assemble your wheel as you usually might and get your skate on! (Just be careful when changing wheels!)
