The
two most common valve types these days are Presta valves and Schrader
valves.
Schrader valves are most commonly found on bikes with wide rims and are the same style you’ll find on most cars.
This
style inflates quite easily with any regular air pump.
Presta
valves are a lot narrower and are commonly found on higher end bikes with
narrow rims.
They
are a little trickier to inflate as they use a manual lock-nut to open the valve
for inflation.
Rather
than purchase a specialised pump you can inflate a Presta valve using a regular
air pump if you have this handy adaptor.
You are buying two and we are giving you
two as spares so we will be sending you four!
