Specialized 29in Turbo Presta Valve Tube With Talc

Specialized presents the 29in Turbo Presta Valve Tube with Talc as their least expensive way to shed 40 grams off your mountain kit. Its thinner tube design is the lightest and most supple option from Specialized, and it's been proven to reduce drag by 13%. Specialized oversized the valve to prevent tearing, and the partially threaded stem provides a clean interface with pumps.
