Ecovelo 700C x 18-32 Orange TPU Inner Tube for Road Bike, 40 g, Long Presta Valve (45 65 85 mm) Racing Bike, Road Racing, Gravel, Trekking, Ultra Light (1 Inner Tube, 85 mm)

Ecovelo puncture proof inner tube designed specifically for 700C racing bikes compatible with different sizes, including 18C/23C/25C/28C/30C/32C. The valve length is available in 45mm, 65mm or 85mm to meet the needs of different bikes. Made from ultra-light TPU material weighing only 40g, this inner tube weighs approximately 1/3 of a traditional butyl tube dramatically improving the acceleration and responsiveness of your racing bike. Superior elasticity and thin structure reduce energy loss and rolling resistance, offering superior abrasion and puncture resistance for agile and smooth ride. Made with a special TPU material, our tubes offer greater resistance to puncture and wear, doubling their durability compared to traditional butyl rubber hoses. Before installation, inspect rim and tyre for sharp objects. Initially inflate under 5 PSI (just round) to position correctly and avoid pinching. IMPORTANT: Never exceed the pressure of 5 PSI (0.35 BAR) when the chamber is out of the tyre; excessive inflation on the outside causes deformation and bulges or irreversible damage.
