Proworks Tyre Iron Bead Stopper

A clever little hands free solution from the brand "Twenty" that helps you change your tyres, especially when you use "Mousse" tubes or other hard tyres. It's used to push the tyre bead down into the drop center of the rim on the opposite side to the one where you use a tyre lever to change tyres.

You attach it to a spoke, so that both of your hands are free. Incredibly clever, and simple.
