MBB Shortboard Racks build on the popular quick release bars of our Longboard Racks, but in a lower cost double seatpost mount. If you only have short boards, usually boards less 7-8 feet in length, these racks are for you! 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. Fit any bike with a seat post, 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.
