The MBB Shortboard Racks provide a super quick and easy installation with a 4 bolt seat post clamp. The bars can be adjusted for angle and height to dial them in just the way you want them. Bars click in for use or click out when they aren't needed, with a simple push of a button. All aluminum and stainless construction for coastal environments. The MBB Shortboard Racks are compatible with all Super73 models and just about any board, although we recommend them for boards 7-8 feet or less. These racks are also popular for carrying kiteboards, snowboards, skis, boogie boards, lawn chairs, and all sorts of similar objects
