⚡ At a Glance
- • Sealing Performance: CNC one-piece design aimed at 99.9% airtightness, reducing leak paths
- • Best for: Road, mountain, folding and e-bike riders converting to or running tubeless tyres
- • Not ideal for: Riders using tube-based inner-tube setups rather than tubeless rims
CNC one-piece presta valve stem engineered for tubeless rims with a secure seal and removable core. Anodised aluminium construction resists corrosion and the kit includes core removal caps and a tool for easy maintenance.
Faster Tyre Inflation – Thanks to large three-hole base
The base uses a large three-hole design that enlarges the air outlet area by 30 percent, raising tyre inflation efficiency by approximately 36 percent during seating. The bigger outlet lets air flow more freely into the tyre bead when using a track pump or compressor.
Quicker tyre seating reduces pumping time during fittings and roadside repairs, getting riders back on the road sooner.
Reliable Airtight Seal – With CNC one-piece construction
CNC-machined one-piece construction minimises joints and potential leak points, contributing to the listed 99.9 percent airtightness. Precision machining helps maintain consistent thread and seat tolerances for a secure rim interface.
Fewer slow leaks and less sealant loss mean longer intervals between top-ups and steadier tyre pressure on rides.
Easy Maintenance – With removable valve core and included removal tool
Removable valve cores allow direct access for adding sealant, clearing blockages or swapping cores, and the kit supplies a dedicated core removal tool and caps. Quick-release core access avoids the need to unmount the stem from the rim for routine maintenance.
Sealant refills and clearing blockages become straightforward jobs, saving time and effort during home maintenance or trail repairs.
