A must-have for changing wheels, removing bearings and more, the SONIC Pro Inline Skate Tool makes skate maintenance a breeze! The long 4mm hex makes it easy to reach tri-skate frame mounting bolts to laterally adjust or remove frames. It is seven tools in one: a long 4mm hex, T25 Torx, Phillips screwdriver, bearing pusher, bearing puller/extractor, bearing press, and a floating space aligner. Made with high strength S2 tool steel but small & light enough to carry around in your portable toolkit, this is handy at home or on the go!
