Aeron Extra Lite Protect 700c TPU Tube Speed and Reliability, Without the Weight The Aeron Extra Lite Protect TPU Airtube is engineered for performance road cyclist seeking the perfect balance of puncture resistance, ultra-lightweight performance and speed. The Aeron Airtubes design absorb less energy, which significantly reduces rolling resistance. Its highly elastic shell deforms under impact to provide extreme durability, while the featherweight design is up to 67% lighter than standard butyl tubes and can be rolled up tightly for a compact size. Featuring a resilient polymer valve stem and superior air retention, the Aeron Extra Lite ensures you spend more time chasing the flats and less time with bulky Co2 tanks. Features TPU construction, up to 66% lighter than comparable butyl tubes 34-44g depending on width variant - cuts rotational weight without sacrificing air retention or ride quality Protection Level 3: Endurance / High Performancepuncture resistance over race-only tubes, with high elasticity and material strength that deforms rather than tears Lower rolling resistance supple TPU wall absorbs road texture deformation with less energy loss than standard butyl tubes Available in (23-28mm) and (28-32mm) tire widthscovers narrow race tires through wider endurance and gravel setups on 700c Presta polymer valve in 42mm, 65mm, and 80mm lengths anti-slip valve surface for secure pump head retention; longer options clear mid- and deep-section rims without an valve extension Ultra-compact packing size rolls tightly to place in a jersey pocket or saddle bag Specifications Valve Type Presta Valve Valve Length42mm / 65mm / 80mm Wheel Diameter700c Compatible Tire Width23-28mm / 28-32mm Material TPU (Thermoplastic Polyurethane)Weight34g (23-28mm) / 44g (28-32mm)Intended Use Road, Gravel | Aeron | Extralite Protect 700C Tpu Tube 700X23-32, 42Mm | Polyurethane
