Continental ContiTech Presta Valve Tube

These tubes are designed specifically for 700c wheels with tire widths between 18mm and 25mm. Please check your tire sidewall to confirm your current width before purchasing.

Your valve length depends on the depth of your wheel rims. You need a valve that extends far enough beyond the rim to attach your pump head; for example, 42mm is standard for shallow rims, while 60mm or 80mm is necessary for deeper aerodynamic wheels.

While these are lightweight tubes designed to reduce rotational mass, they are built with seamless butyl rubber and individually tested for reliability. They are suitable for daily use, though their thinner construction makes them slightly more susceptible to punctures than heavy-duty touring tubes.

Yes, reducing rotational weight at the tire level is one of the most effective ways to improve acceleration and handling. By shaving off nearly 30% of the weight compared to standard tubes, you will notice a snappier feel, particularly when climbing or sprinting.

Yes, these tubes can be used in tubeless-ready rims as long as you are running a clincher tire setup. Ensure your rim tape is properly installed to prevent the tube from rubbing against spoke holes.
