- • Seal Reliability: Large soft rubber base and lock nut form an airtight seal for valve holes up to 8mm
- • Best for: MTB and road cyclists running tubeless tyres who want lightweight, corrosion-resistant valves
- • Not ideal for: Riders who still use inner tubes, because these are not compatible with tubed tyres
Lightweight anodised aluminium stems include removable valve cores and lock nuts. Kit contains two 48mm stems, spare covers and a valve core remover.
Reliable, leak-free rides - With a large soft rubber base and lock nut
Large soft rubber base compresses against the rim hole, while a threaded lock nut secures the stem and prevents rotation. Valve core is removable to allow direct sealant access when needed.
Airtight sealing reduces sealant loss and keeps tyre pressure steady during long rides. Less time topping up and fewer mid-ride surprises for frequent tubeless users.
Lightweight and corrosion-resistant - With anodised aluminium construction
Anodised aluminium offers a low-mass alternative to heavier metals and forms a protective oxide layer that resists rust. The stems are 48mm long to suit common rim depths.
Lower weight on the wheel helps keep rotating mass down and the finish stays serviceable in wet conditions. Durable construction suits riders who store bikes outdoors or ride year-round.
Quick maintenance and sealant top-ups - With removable valve core and included remover tool
Removable valve core design permits removal of the insert for pouring sealant or clearing blockages. The kit includes a dedicated valve core remover and spare valve covers for routine tasks.
Fast at-home tyre maintenance avoids workshop trips and makes mid-ride sealant top-ups straightforward. Handy for riders who fit or seal tyres themselves.
