Maintaining correct tyre pressure is essential for safe and efficient cycling, but a faulty valve core can lead to slow air leaks that compromise performance. This aluminium alloy valve core offers a direct replacement for worn or damaged cores in bicycle vacuum inner tubes, providing a simple fix without replacing the entire tube. With options ranging from 40mm to 120mm in multiple colours, you can select the exact size and finish to match your bike's specifications and aesthetic preferences. The set includes necessary sealing components such as transparent washers and seal rings, enabling a hassle-free installation.
Features and Construction

This valve core is built from a robust aluminium alloy, offering a lightweight yet sturdy solution for maintaining air pressure. The design focuses on straightforward replacement and compatibility with standard bicycle inner tubes.
Material and Build
The core is made from an aluminium alloy with metal internals, ensuring durability and resistance to corrosion. The valve core body is slim and precise, designed to fit securely within the inner tube valve stem. The accompanying transparent washers and seal rings create an effective barrier against air leakage.
Size and Practical Fit
Available in lengths of 40mm, 60mm, 80mm, 100mm, and 120mm, this valve core suits a wide range of bicycle inner tube valve configurations. The compact design makes it easy to handle and install with basic tools. Choose the length that matches your existing valve for a seamless swap.
Uses and Placement

This replacement valve core is ideal for cyclists who need to fix a persistent slow puncture or leak around the valve area. It can be used on road bikes, mountain bikes, and many other bicycles that use standard vacuum inner tubes.
Event or Professional Use
For bike mechanics or enthusiasts preparing for races or long tours, a reliable valve core is critical. Keeping spare cores in different lengths ensures quick repairs on the go, reducing downtime and maintaining performance.
Everyday Home Use
Casual riders will find this valve core a practical addition to their maintenance kit. Replacing a worn core is a simple DIY task that saves time and money, helping to keep the bike ready for daily commuting or weekend rides.
Benefits and Buying Value

This product offers an affordable way to extend the life of your existing inner tubes. Its multi-length and colour options provide flexibility, while the included sealing accessories ensure a secure fit.
Reuse and Low Maintenance
By replacing just the valve core rather than the whole tube, you reduce waste and save on replacement costs. The aluminium alloy construction resists wear, and the included washers help maintain a tight seal over time.
Why Choose This Product
With a range of lengths from 40mm to 120mm and colours like black, blue, orange, and red, this valve core offers customisation not always available in standard replacements. The inclusion of sealing rings and washers in pair sets adds further value, making it a complete solution for a common bike issue.
