Turbo Presta Valve Tube with Talc

The least expensive way to ditch 40 grams of rotating weight on road tubes! Patented, oversized, 4.8cm valve base prevents tearing. Partially threaded valve stem for cleaner interface with pumps. Our lightest and most supple tube offering. The Turbo ultralight tube, with patented valve and valve base, is proven in rolling resistance testing to reduce drag by as much as 13% per wheel.
