Continental ContiTech Presta Valve Tube

These tubes are engineered to be nearly 30% lighter than standard butyl tubes. Depending on your choice of valve length, you are looking at a total weight of 65 grams for the 42mm version or 70 grams for the 60mm version.

Seamless construction eliminates the potential weak points found where rubber is joined together. This results in a more consistent, reliable tube that maintains air pressure more effectively and reduces the risk of sudden failures.

The valve length you choose depends entirely on the depth of your wheel rims. You need a valve long enough to extend past the rim bed so your pump head can securely attach; if you have deeper aero rims, you will likely need the 60mm option.

While these are lightweight and designed to improve acceleration and tire suppleness, they are durable enough for regular road cycling. Because they are individually tested for quality, they offer a reliable performance upgrade for both training rides and competitive events.

These tubes are specifically sized for 650c tires with a width range of 18mm to 25mm. Please verify your tire sidewall markings to ensure your setup falls within this range before purchasing.
