Poison is Atom's new 'go-to' wheel for ANY surface. Never worry about sliding again! Atom noticed that many derby skaters use outdoor wheels which are normally narrow and WAY too sluggish. To answer your needs, they've created Poison. Now you can have the best of all worlds: grip, roll AND amazing lateral push! Poison provides awesome grip without that 'sluggish marshmallow" feeling which allows for more roll. Featuring super sick graphics on a bright green core, Poison will blow your competitors off the derby track! Perfect for: Outdoor Tracks, Slick Sport Courts, Banked Tracks, and Dirty Wood Floors.
