Ideal for all cyclists – Whether you’re a competitive racer or a weekend rider, alloy valves provide long-term reliability, smoother rides, and enhanced tyre pressure control.

A lighter bike = a faster ride 🚴‍♂️. Alloy bike valves reduce weight, improve air retention, and enhance performance—giving you the edge on any terrain. Would you make the switch?

The Role of Bike Valves

Valves may seem inconspicuous, yet they fulfil two pivotal functions. First, they maintain adequate air pressure by forming a tight seal inside the tube or tubeless setup. Second, they permit precise adjustments to suit various riding conditions.

Maintaining Air Pressure

Proper pressure aids in reducing rolling resistance, improving comfort, and enhancing grip.
A secure valve mitigates air loss over time.

Adjustable Pressure Control

Riders can fine-tune tyre pressure to match weather, terrain, or personal preference.
Quick changes prove vital in competitive cycling when conditions shift abruptly.

Valve Types

Presta: Preferred on high-performance road, gravel, and many MTB setups due to their slim design and compatibility with narrower rims.
Schrader: Common in recreational cycling because they are wider and simpler to inflate at most standard pumps.
Dunlop/Woods: Less frequent in modern competitive scenes but still used in certain regions.

Our Legacy in Valves

Began with producing valves, nipples, and hubs before expanding to comprehensive wheelsets, tubes, and cassettes.
The Eclipsetubes range carries forward that tradition, incorporating an alloy valve designed for reliability and ease of use.

Why Alloy? A Brief Overview

Not all metals share the same characteristics. Traditional valves fashioned from brass or steel remain functional but can be heavier than necessary for competitive riding. Alloy valves, particularly aluminium-based ones, serve as a highly effective alternative.

What is an Alloy Valve?

Typically derived from aluminium and blended with other elements to enhance strength while minimising weight.

Shift from Conventional Metals

Brass or steel valves endure extensive wear but add unnecessary grams, especially noticeable in racing scenarios.
Alloy valves present a superior strength-to-weight ratio, a critical factor for those chasing marginal gains.

Patented Alloy Valve in Eclipsetubes

Specifically engineered to complement our TPU (Thermoplastic Polyurethane) tube material.
The union of lightweight TPU and a robust yet feather-light valve results in a tube that balances performance with durability.

Key Benefits of Alloy Bike Valves

Lightweight Construction

The rotational mass at a wheel’s circumference has a pronounced effect on acceleration and agility. Alloy valves cut unnecessary weight:

Performance Boost: Even small weight reductions can translate into quicker accelerations, especially when climbing or surging.
E.Dubied & Co Example: Some of our Eclipsetubes weigh under 20 g for road applications, largely due to the aluminium-based valve stem.

Durability and Strength

Aluminium alloys have been refined to handle a wide range of pressures:

High PSI Tolerance: Road racers may use pressures from 70 psi to beyond 100 psi; an alloy valve ensures structural integrity under these stresses.
Reinforced Design: Our patented alloy valve exhibits minimal flex and resists impact, especially crucial in cyclocross or gravel events.

Corrosion Resistance

Steel and brass valves can corrode over time, especially in wet or salty conditions:

Protective Finishes: Many alloy valves, including ours, receive specialised treatments or anodised coatings that significantly lessen rust issues.
Longer Lifespan: Fewer replacements save effort and resources in the long run.

Consistent Inflation and Deflation

Efficient inflation or deflation stems from quality machining:

Smooth Threading: Properly machined threads ease pump attachment, reducing wear on both the pump head and the valve.
Reliable Sealing: A well-fitted alloy stem minimises slow leaks and retains pressure consistently.

Integration with Tubes and Tyres

Our Eclipsetubes combine a TPU body with a patented alloy valve, creating a single, streamlined system:

Reduced Risk of Pinch Flats: A stable valve seal prevents internal tube shifts that sometimes lead to pinch flats.
Easy Handling: Lighter tubes are quicker to install or remove during roadside repairs.

Environmental Considerations

Durability and weight savings carry eco-friendly benefits:

Less Waste: Alloy valves have a longer service life, cutting down on frequent disposals.
Carbon-Neutral Shipping: We aim to offset the environmental impact of transportation by funding direct air capture and other sustainable projects.

Why Professional Cyclists Prefer Alloy Bike Valves

Top Performance in Demanding Conditions

Tyres in elite races often run high pressures for optimised rolling resistance.
Gravel or cyclocross riders depend on stable valves that resist mud, water, and debris.

Marginal Gains Philosophy

Professionals address every component, no matter how small.
A consistent valve preserves the carefully chosen tyre pressure that can decide race outcomes.

Efficiency in Maintenance

Quick wheel changes are essential; valves that allow rapid pump attachment save time.

Whether it’s a Four8 aero wheelset or an All Road Carbon model, professional riders and ambitious amateurs rely on the synergy of innovative design and proven reliability.

Alloy Valves in Tubeless Setups

Tubeless technology reduces pinch flats, improves traction, and can lessen rolling resistance. Although many riders embrace tubeless entirely, others opt for TPU tubes in certain situations. Alloy valves accommodate both preferences efficiently.

Growing Tubeless Popularity

Road, gravel, and mountain biking communities recognise benefits like fewer flats and the capacity to run lower pressures for better grip.
High-end bikes increasingly come tubeless-ready from the factory.

Advantages of Alloy Valves in Tubeless

Removable Cores: Makes adding sealant straightforward.
Secure Seal: Precision-machined valves match up with rim beds to prevent air escapes.
Adapts to Various Rim Depths: Deeper rims require longer stems; alloy valves offer the needed lengths with minimal weight penalty.

Practical Maintenance Tips

Cleanliness: Rinse the valve core periodically to remove dried sealant or debris.
Valve Core Replacements: Keep spares for quick swaps; a blocked core can ruin a ride or race if not promptly fixed.

Eclipsetubes and Hybrid Use

Some racers choose TPU tubes inside tubeless-ready tyres for specific events, combining the protective layer of a tubeless tyre with the ease of a tube.
The alloy valve remains a solid anchor, ensuring reliable inflation regardless of setup.
