Well....nowadays its not so clear because there are many different types of rocker. The best thing to do is go on each individual company's site and check out which rocker tech they are using. Here is the info on the Hero. For info on the rocker click on the word "V-Rocker" down in the tech area.
Men's Hero Limited Snowboard | Burton Snowboards
Here is the description for the V-Rocker:
A three-stage rocker thatís equally fun from park to pow, V-Rockerô features a center rocker between your feet, with additional rockers outside each foot that lift the tip and tail completely off the snow. Along the Channel zones, we added Pressure Distribution Edges for enhanced grip and power that balances the boardís loose and forgiving, skate-like feel. Together, the V-Rocker package energizes edge control while disengaging tip and tail contact points to create a catch-free feel thatís incredibly forgiving, floaty, poppy, and fun on all terrain.
