ERE Research TUBUS Butyl 700c Inner Tube Presta Valve

Tubus butyl inner tubes are the right complementary solution to go with our Ere clincher tires, we make them with a 0.9mm wall thickness to keep them light and supple, so the true performance of the tire-tube-wheels combination is always optimal.The weight of a Tubus innertube is 99 gram. (deepening on size).Our Tubus inner tubes have a black valve stem so they fit nicely with black alloy and black carbon rims/wheels and therefore compliment the overall finish of the wheel.The valve core is removable, in order use proper valve extenders and it comes with a black valve cap to keep dirt out of the valve itself and continue your ride without inner tube concerns.GeneralWeight99 gramValvePresta / FrenchValve colorBlackRemovable coreYes Valve coverBlack MaterialButyl Valve extender compatibleYes - not included Wall thickness0.9 mm ColorBlackTechnology20 - 28CValve length48mm / 60mmTyre width20 - 28CRim size700C/28"Size ETRTO20-622 / 28-622Technology28 - 38CValve length48mm / 60mmTyre width28 - 38CRim size700C/28"Size ETRTO28-622 / 38-622
