Schwalbe 27.5+' SV21FE Aerothan Presta Valve 40 mm Chamber

Uniquely light and extremely stable. Schwalbe revolutionary new tube made of Aerothan achieves previously unattainable top values in terms of elasticity, weight and puncture resistance and does not require any rubber. When it comes to racing with a tube , the Aerothan Tube Race is the first choice. Because it impresses with its low rolling resistan... morece and dynamic, smoother driving dynamics. Compared to butyl tubes, a weight saving of 100 grams and more can be achieved for the entire bike. You can rely on the Aerothan Tube Race not only for its excellent puncture protection, but also when driving downhill: it remains absolutely heat-resistant even after several emergency brakes with rim brakes in quick succession. Aerothane tube: Aerothan is a material that completely redefines the bicycle tube: extremely light, highly puncture-proof and designed for the lowest possible rolling resistance. The revolutionary tube made of Aerothan achieves previously unattainable top values in terms of elasticity, weight and puncture resistance. Especially for racing bikes, MTBs and trekking bikes.Features:- Consistently light up to the valve - around 40% lighter than a comparable Schwalbe Extralight tube- Redefined puncture protection - the material suddenly prevents air loss- Minimum rolling resistance - maximum driving dynamics- Extremely heat resistant - approved for rim brakes- Stable driving behavior - even at low air pressures- Easy assembly - without slipping or getting jammed- 100% recyclableSpecifications:- Material: Aerothane (thermoplastic polyurethane)- Intended use: Racing bike- Compatible sizes (inches): 27.5 x 2.40 to 27.5 x 3.00- Compatible sizes (ETRTO): 62-584 to 75-584- Valve length: 40 mm- Valve standard: SV (Presta, Sclaverand, racing bike valve)- Weight according to the manufacturer: 41g- Weight weighed: 47g
