Hey All,

Anyone know what kind of valve extender I need for a hed jet 90 with a continental sprinter tubular? I see that there are 2 kinds...some for "removable core stems" and some for "regular stems". Anyone have a clue? Does the conti sprinter have a removable core stem?

I know one allows you to use a pressure gauge, and one does not...but that is about it.

Thanks,

Philbert
