Our Turbo Presta Valve Tubes w/ Talc are the least expensive way to ditch 40 grams of rotating weight that we know of. They're our lightest road tubes, and have been tested to reduce drag up to 13% per wheel.
Packed in talc for easier installation. 4.8cm valve base prevents issues of valves tearing off. Smooth at the top for easier pump head insertion and reduced wear on pump internals. Thinner tube design saves approximately 40 grams of rotating weight. Thickness: 0.6mm
