Deemount Bicycle Vacuum Tubeless Valve French 40mm 60mm 80mm Aluminum Valve Core

Maintain stable tyre pressure and reduce punctures with this Deemount tubeless valve set. Designed specifically for tubeless bicycle wheels, the valve creates a vacuum seal that minimises air leakage. It comes as a pair with the necessary fitting tools, making installation straightforward for both road and mountain bikes. Constructed with an aluminum rod, a copper core, and an alloy cap, each valve weighs only about 4.3g—light enough not to affect wheel balance. Available in four color choices (black, blue, orange, red) and three length options (40mm, 60mm, 80mm), you can select the best fit for your rim depth and aesthetic preference. The French mouth type is compatible with standard tubeless valve holes, ensuring a snug fit.

Features and Construction

Every component of this valve is chosen for functional reliability and ease of use. The combination of materials supports a durable seal that helps keep tyres inflated correctly over time.

Material and Build

The valve body uses an aluminum rod for a lightweight yet rigid structure. A copper core forms the main sealing element, and an alloy cap protects the valve from debris. All three materials work together to resist corrosion and maintain a consistent fit within the rim hole.

Size and Practical Fit

With three length options—40mm, 60mm, and 80mm—the valve can be matched to different wheel rim depths. The French mouth type fits most standard tubeless rim valve openings, and the included tools assist with secure tightening. At approximately 4.3g per piece, the valve adds negligible rotational weight.

Uses and Placement

Tubeless valves are essential for any bicycle running a tubeless tyre setup. They allow for lower tyre pressures and reduced risk of pinch flats while maintaining a reliable seal.

Event or Professional Use

For cyclists preparing for races or long rides, consistent tyre pressure is critical. This valve set ensures minimal air loss during high-speed or high-load use. The pair pack covers both wheels, and the included tools simplify setup before an event.

Everyday Home Use

Home mechanics and casual riders benefit from the simple installation and durable construction. The valve holds up to regular inflation and deflation cycles, making it a practical replacement for worn or damaged tubeless valves.

Benefits and Buying Value

Choosing a dedicated tubeless valve improves the reliability of your tubeless system. This Deemount pair offers straightforward installation, material quality, and color options without unnecessary complexity.

Reuse and Low Maintenance

Once installed, the valve requires minimal attention beyond occasional checks of the core and cap. The aluminum and copper construction resists typical wear from tyre changing and weather exposure.

Why Choose This Product

The valve pair covers both wheels, tools are supplied, and you can pick the length and colour that best match your bike. This combination makes it a convenient, no-hassle upgrade for any tubeless bicycle setup.
