An adapter that attaches to the Presta valve and is compatible with the Schrader valve. I need to inflate on the go, but I don't have a pump! However, there is a gas station in front of me, so if it is compatible with the American style, it may be possible! It is an adapter that stands up in such a case.
CRUD CAPSThis item is also required when you want to attach the valve cap of the above to the Presta valve.
