In an effort to offer different color choices for the Quad Lock Bike Mount we have teamed up with Shapeways to produce 3D printed replacement locking collars for the Bike Mount Pro in 6 different colors. The parts are 3D Printed by Shapeways and sent directly to your door. The finish is not quiet as smooth as an injection molded part but it functions just the same. So if you're the type that likes your bike to be color coordinated with your gear check them out now!
