Our ultimate monocoque carbon pre-preg wave boom is designed for expert riders who demand knife-like precision from their equipment. The XC-S Wave boom now offers the same precision performance as the XC boom but with a slimmer diameter grip at 25mm vs 27mm. This boom offers instantaneous control with its increased torsional rigidity and square profile tail end. Allowing zero lag time from flexing connections. Giving the cosiest sensation you have ever felt while holding a boom, and now allowing you to sail longer and grip easier with the narrower diameter arms.
