The Viper has been redesigned into two new yo-yos. One with hubstacks and the other is this version, the Viper Neo. The Neo is fast and versatile on the string using the new Gecko Pad that is a molded silicone response system that clicks into the silver annodized hub. It also uses the patented Henry's speed bearing system. Outfitted with soft rubber rims the Viper Neo is very durable with many applications.
