TPU Tube - 29" (700c) - 60mm Presta Valve

The highest grade of micrometer-thick TPU deployed across seven sealed layers maximizes 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.

Note: Due to the reduced wall thickness they are a little more prone to be harmed by potential heat during long and hard brakes so they are only ready for use in bikes with disc brakes.
