Shad Pin System X021PS is an innovative tank fixing kit to connect a Shad bag to the bike in a simple and safe way. Three or four gas cap screws are replaced with discrete "pins", making installation very simple and fast. In a few minutes and with just the use of a screwdriver and an allen screw you will have finished the installation! The new Pin System Shad is a fully integrated system: the fixing mechanism is in the bag, not on the bike. You can then mount one of the Shad tank bags with just one click.
