Industry Nine Tubeless Valve Stems

These 40mm stems are designed to be compatible with most standard tubeless-ready mountain and road wheelsets. However, you should confirm that your rim profile is compatible with a 40mm length to ensure you have enough clearance for your pump head.

Industry Nine engineered the internal design of these stems to optimize airflow and minimize the nooks where sealant typically pools and dries. This design helps keep the valve core clear, ensuring you can easily adjust tire pressure or add more sealant without blockage.

Yes, they are compatible with all standard tubeless sealants. The aluminum construction is durable and resistant to the chemical properties found in common latex-based sealants.

Installation is straightforward and typically requires only a standard wrench or pliers to tighten the lock nut. You do not need proprietary tools, though a valve core tool is handy for removing the core to add sealant later.

Absolutely. The aluminum used is chosen specifically for its balance of high strength and low weight, making it robust enough to handle the vibrations and impacts associated with aggressive trail riding while keeping your rotational mass low.
