Continental TPU Tube - 700 x 25 - 35 / 29 x 1.0 - 1.4 100mm Presta Valve

ContiTPU tubes feature the highest grade of micrometer-thick TPU deployed across seven sealed layers to maximize airtightness and durability. The tubes are uncolored 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. The valve is internally threaded to allow for the use of valve extensions or a replacement valve core.These tubes are designed for performance-focused and space-saving road, gravel, and MTB riders. The seven-layer lightweight TPU design and construction provides low rolling resistance while remaining lightweight and durable within a small packing size. The tubes are easy to repair with a repair kit included and are designed for disc brake use only.
