Continental TPU Presta Valve Inner Tube

TPU TUBES
A seven-layer lightweight TPU Inner Tube for performance-focused and space-saving road, gravel and MTB riders. ContiTPU is premium, lightweight yet durable and suitable for both road and off-road riders. The highest grade of micrometer-thick TPU deployed across seven sealed layers maximises airtightness and durability. The tubes are uncoloured to further ensure the highest material quality and prevent air retention issues caused by dye-related surface imperfections. Every ContiTPU tube is quality-checked post-production. The base of the valve shaft is slightly conical in shape to improve fit to the wheel rim and reduce unwanted movement, while the valve is internally threaded to allow for the use of valve extensions or a replacement valve core.

IMPORTANT INFORMATION
1. TPU tubes must never be used in conjunction with rim brakes. Excessive heat exposure can lead to a sudden loss of air pressure.
2. Use suitable rim tape to protect the TPU tube. Otherwise, it can become damaged.
3. During mounting, the TPU tubes must not be inflated over 0.3 bar. Over-inflation during this part of the process can excessively stretch the tube and render it unusable.
4. Ensure the valve hole in the rim is the correct diameter. If the valve hole is too large, the valve can twist or shear off.
5. Pay close attention when mounting the tube. Always ensure the tube or valve isn't trapped, twisted or damaged.
6. TPU tubes must never be re-used with a smaller tire! If you are mounting a smaller tire, then it is necessary to use a new tube.
