This mighty adapter will allow you to use a schrader pump to inflate your presta valve tyres. Extremely useful to have in the glove-box so you can pump your tyres up at petrol stations, which we do quite regularly. A must have for every mountain-bikers car. Often your pump isn't strong enough to seat tubeless tyres but those petrol station pumps generally do a great job! :)
