Based off of our experience making bikes with full custom geos we noticed some patterns in sizing. Based on that knowledge we decided to create 12 pre designed geometries that should fit the majority of riders out there. Each Argonaut is Custom Tailored for layup and ride quality but with pre designed geometries we can save you some money and build time. If you don’t fit any of these sizes then we still have the capability to create a fully custom geometry to your exact specs.
