Saris may have been bought earlier this year, but they are excited to add some new bike products this summer. They last released the MHS (Modular Hitch System) with their bike trays. The MHS allows users to customize their hitch rack, like above, where they have an upcoming single-arm bike rack with their cargo tray. The attachments should be relatively easy to install/uninstall. Keep an eye out for the single-arm rack later this year.
