The Challenge Latex Tube 700 x 23/28c is a high-performance inner tube designed for cyclists seeking superior speed, comfort, and rolling efficiency. Made from premium seamless latex, it is lighter, softer, and far more supple than standard butyl tubes, adapting dynamically to tire shape during cornering and rolling. This unique one-piece seamless construction eliminates bumps and puckers at the valve area, ensuring a smooth, balanced ride and improving overall wheel performance.
According to multiple international tests (Germany, Finland, Belgium, the Netherlands, the UK, and the USA), latex inner tubes like this can save more than 3 watts per wheel compared to standard butyl tubes, making them a simple yet effective way to enhance your cycling performance. The tube comes with a removable core Presta valve, compatible with inline and external valve extenders.
FEATURES & ADVANTAGES
Seamless one-piece latex design: Smooth and balanced ride with no valve bumps or puckers.
Lighter, softer, more supple: Reduces rolling resistance, improves comfort, traction, and cornering.
Enhanced performance: Saves energy with lower rolling resistance—ideal for competitive road cycling.
Elastic and durable: Latex stretches up to 7–8 times its original size for excellent flexibility and reliability.
Puncture Protection System (PPS): Latex stretches and conforms around potential puncture points, slowing air loss in case of minor punctures.
Removable Presta valve core: Compatible with inline and external valve extenders.
Lightweight construction: Reduces rotational mass for faster acceleration and improved handling.
Optimal sizing: 700 x 23/28c fits standard road tires, suitable for performance and endurance riding.

USAGE NOTES & WARNINGS
Pressure retention: Latex is more gas-permeable than butyl; check tire pressure before each ride.
Installation caution: Suppleness can increase risk of pinch flats if not installed carefully. Talcum powder is included to aid installation.
Handling: Latex may be slightly sticky; a light talcum powder coating helps ensure smooth installation.
