The least expensive way to ditch 40+ grams of rotating weight is with the Turbo Talc Tubes. A patented, oversized 4.8cm valve base prevents tearing, while a partially threaded valve stem provides a clean interface with pumps. Specialized's lightest and most supple tube offering, it's also been proven in rolling-resistance testing to reduce drag by as much as 13% per wheel.
