The Schwalbe Tire Booster allows easy set-up and sealing of tubeless tyres without the need for a specialist compressor. Just use a conventional floor pump to charge the Presta valve on the top of the Tire Booster. Flick the quick-release lever and the air quickly releases to seat the tyre to the wheel rim. This is a lightweight (435g) and portable solution to inflating tubeless tyres.""
