absoluteBLACK, renowned for its innovative cycling components, has unveiled its latest advancement in tubeless technology: the Aether Carbon Ultra-Light Tubeless Valves. These valves represent a significant leap in design, combining cutting-edge materials and engineering to deliver unparalleled performance for cyclists.
Revolutionary Carbon-Reinforced Polymer Construction
Departing from traditional aluminium designs, absoluteBLACK has engineered these valves using carbon-reinforced polymer injection. This material choice offers a density approximately half that of aerospace-grade aluminium, resulting in a substantial weight reduction without compromising durability. The carbon-reinforced polymer also allows for more intricate internal geometries, enhancing the valve’s overall performance. Sealing elements remain rubber to ensure reliable airtight performance. The construction is patent pending, and the external design is already protected by granted patents.
Innovative Bottom-Sealing Mechanism
In a nod to early valve designs from 1915, absoluteBLACK has adopted a bottom-sealing mechanism. This design places the sealing interface at the base of the valve, simplifying the internal structure and contributing to reduced overall mass. This approach also facilitates a more direct internal air path, enhancing the efficiency of the tubeless system.
Lightweight Design for Enhanced Performance
Weighing just 2.6 grams per valve (including a 0.6g cap), the Aether valves are among the lightest available on the market. This significant weight reduction minimizes rotating mass at the wheel, a detail appreciated by riders focused on overall bike weight and efficiency. The valves can be used without the cap, reducing the mass to a mere 2.0g.
Compatibility and Availability
The Aether Carbon Ultra-Light Tubeless Valves are fully compatible with standard Presta pump heads, ensuring ease of use for cyclists. They are available in two lengths to accommodate various rim depths:
- 18–30mm rim depth (2.6g per valve)
- 30–50mm rim depth (3.1g per valve)
Priced at $29.95 USD/€25.95 EUR for a set of two valves, they are available now. For more information, visit the absoluteBLACK website.
In a market where tubeless valve development often focuses on high-flow designs aimed at mountain biking, which can come with added bulk or high price, absoluteBLACK’s Aether valves take a different approach—prioritising low weight, compact form factor, and compatibility with road and gravel setups. This innovative design offers cyclists a practical solution that enhances performance without compromising on durability or ease of use.
