Continental TPU Tube

Continental's TPU tubes deploy the highest grade of micrometer-thick TPU across seven sealed layers to maximizes airtightness and durability. They are also uncoloured to further ensure the highest material quality and prevent air retention issues caused by dye-related surface imperfections. 

700 x 25-35c = 35g
700 x 40-60c = 43g
650b x 40-60c = 43g

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. 

Safety: 

• TPU tubes must never be used in conjunction with rim brakes. Excessive heat exposure can lead to a sudden loss of air pressure.
  
• During mounting, the TPU tubes must not be inflated over 0.3 bar / 4 psi. Over-inflation at this point can excessively stretch the tube and render it unusable. 
• Never re-use TPU tubes with a smaller tire! If you are mounting a smaller tire, then you must use a new tube.
