ContiTPU tubes feature the highest grade of micrometer-thick TPU is 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, while the valve is internally threaded to allow for the use of valve extensions or a replacement valve core.Designed for performance-focused and space-saving road, gravel and MTB ridersSeven-layer lightweight TPU design and construction provides low rolling resistanceLightweight and durable within a small packing sizeEasy to repair, with repair kit includedDesigned for disc brake use onlyItem SpecificationsISO Diameter584 / 650b / 27.5"ISO Width (mm)40ISO Width (mm)41ISO Width (mm)42ISO Width (mm)43ISO Width (mm)44ISO Width (mm)45ISO Width (mm)46ISO Width (mm)47ISO Width (mm)48ISO Width (mm)49ISO Width (mm)50ISO Width (mm)51ISO Width (mm)52ISO Width (mm)53ISO Width (mm)54ISO Width (mm)55ISO Width (mm)56ISO Width (mm)57ISO Width (mm)58ISO Width (mm)59ISO Width (mm)60Labeled Size 650 x 40 - 60Labeled Size27.5 x 1.6 - 2.4Shaft TypeSmoothTube CompoundThermoplastic ElastomerValve CoreRemovableValve LengthLong Presta Valve 56-74mmValvePresta Long 56-74mmWeight43 Continental ContiTPU Tube Tubes EAN: 4019238057904
