Very similar to the High Performance Series, the Grom Models utilize Xanadu's revolutionary foils, rockers, and outlines. These boards are meant for pushing the limits in good conditions worldwide. By working with young groms in California and abroad, Xanadu has formulated a new series of surfboards focused on increasing the performance of younger surfers that have a bag of tricks, solid rail game, and can throw big airs. This is what the NSSA guys order for good waves from shoulder high to well overhead.
