uice Sapphire 59mm/91a Narrow Blue 4Pk Wheels (5991SAP):
Finally a refreshing innovation in wheels, developed specifically for Derby at all levels of play. A collaborative partnership between the premier wheel manufacturer and players, the new technology delivers grip when you need grip, roll when you need roll and energy when you need it most.
The Martini Series features an inner urethane core, allowing the running surface of the wheel to remain on the floor longer delivering more grip just when you need it most. Compression on your stroke drives energy into the core, and then expends it during the roll, giving you that added punch. More grip, longer roll, and less wasted energy--that is what Juice Wheels delivers to every player who wants an unfair advantage on the track. Pick your poison... 3 to choose from.
Playing Derby on new Juice Wheels is different than planing on the old style speed wheel technology. Juice Wheels are not for everyone, only Derby players like you who want more grip when you turn, more roll during the jam, and less wasted energy to outlast your opponent.
