Road Turbo Presta Valve Tube With Talc

As Specialized's lightest and most supple tube offering, the Road Turbo Presta Valve Tube with Talc is one the least expensive ways you can ditch 40-plus grams of rotating weight on the road. It comes packed in talc for easier installation, and the smooth top makes for easier pump head insertion while the partially threaded valve stem provides a clean interface with said pump. Not to mention, it's also been proven in rolling-resistance testing to reduce drag by as much as 13% per wheel.
