Skull Skates 'Skulls' wheelset. High rebound speed formula. Poured 97A material available in 58mm [35mm wide]. Tired of the insane rock hard wheels that are only good for ice smooth surfaces and blunt slides? The 97A hardness brings us back to the days of more all around surface destruction while still being hard enough to destroy a pool or bowl. Older weathered skateparks, imperfect rougher street spots and ditches beware. Dayglo green. Set of 4.
