Mirage GRS Frameuitzetter

The Mirage GRS Frame Extender is a handy tool for changing your rear tyre without removing the wheel. On city bikes or electric bikes with a closed chain case, it can be a tedious job when the inner tube of your rear wheel has gone flat and you need to change it. But not with the Mirage GRS frame expanding tool! By placing this tool between your chainstay, you can spread them out until you have enough room for the inner tube to fit through.
