i72 Tubeless Valve Stems 40mm Presta Pair - Brass Made with Core Remover Tool, Round Rubber Base with O-Ring for Better Sealing

Perfect fit for going tubeless

Perfectas para mis ruedas

Ive gone through a lot of valve stems in my time using tubeless tires. These are by far the best-built Ive seen - a bit more substantial than other brands Ive used. They also have removable cores, which is huge for those of us adding sealant without wanting to pop the tire bead off. Im going to see if they have a 60mm length version for use with more aero-style rims.

These mounted easily and had no leak issues at all.

Works great seals well onto the rim.
