Stan’s Exo-Core Tubeless Valve Stems (Black) (Pair) (37mm)

Stans Exo-Core Tubeless Valve Stems Description:

The Stans Exo-Core Tubeless Valve Stems are a revolutionary multi-piece tubeless valve stem that is designed to eliminate clogging due to the use of tubeless tire sealant while also allowing a high volume of air to push through when inflating and setting up tubeless tires. The base of these stems have a very large bore and multiple holes on the part of the valve that sits inside the rim that will allow air and sealant to flow into a tire even if there is a tubeless tire insert inside the rim. Add in the use of materials that resist corrosion and the ability to perform micro adjustments to tire pressure without any wrenches or other tools, and you have a set of valves that make it easier than ever to reap the benefits of going tubeless.

Note: Listed length of these valve stems need to be at least 17mm longer than the depth of the rim that they are going into for proper fit and functionality.

Features:

• Aluminum valve stems feature an oversized bore to make it easier for tire sealant and air to flow into tire
• Revolutionary multi-piece design with external sealing and an all-brass core work together to eliminate clogs and make it easier to keep valve clean
• Upper extension has an easy to grip external profile that allows for easy micro fine tuning air pressure changes by loosening this part of the stem by 1/8 of a turn, or rapid air pressure changes by loosening the upper part of the valve stem by one full turn
• Tapered elliptical rubber stopper fits a wide variety of inner rim shapes to ensure an airtight seal on tubeless ready rims that are drilled to accept presta valves
• Stem base has multiple vent holes to allow air to freely flow in tubeless even if the tires have a tubeless tire insert
• Unique “twist and pull” style cap is easy to use, and will stay securely in place even over rough terrain
• Compatible with any pump that can air up a Presta valve
