Zefal Valve Adaptor FV Presta To Car Pump

These wee brass adaptors can be real ride savers if, for instance, you ride with a Presta pump for your bike, but your children's bikes come with Schrader (car type) valve tubes

The Zéfal Presta to Schrader Adaptor enables you to inflate a Presta valve tube with a Schrader valve pump, such as a car foot pump or a 'free air' pump at the garage.

Weighing just 5g apiece, there is no reason not to store one of these adaptors in situ to one of the wheels on your bike. That way, the adapter will be ever available should you (or your ride buddies) ever need it
