Continental ContiTech TPU Inner Tube

No, these tubes are specifically engineered for disc brake systems. Because TPU material is sensitive to the heat generated by rim braking surfaces, using them with rim brakes could lead to failure.

At just 35g, this tube is significantly lighter than a standard butyl rubber tube, which typically weighs between 100g and 150g. This reduction in rotational mass can make your wheels feel more responsive during acceleration and climbing.

Yes, they feature a removable Presta valve core. This allows you to easily install valve extenders if you are using deeper-section aerodynamic rims.

The installation is largely the same, but you must be careful not to over-inflate the tube outside of the tire, as TPU can stretch and deform permanently if not contained. Always ensure the tube is properly seated within the tire casing before inflating to your desired pressure.

The specially molded conical base provides a more secure, snug fit against the rim hole compared to standard flat-base valves. This design helps minimize movement and friction at the valve stem, reducing the risk of tearing or leaks at that critical junction.
