Ventiilinjatke Continental 60mm, 2kpl.

Can be used on any presta tube with a screw out valve (replaceable valve core)

Can be doubled up to create a longer extension

With this system, your original valve core is always at the top of the extension, unlike some systems which screw over the valve and leave the valve core unreachable inside the rim and require users to leave the valve open at all times

Pair (2 pieces)

Includes tool
