Specialized Turbo Pre-Talc'd 29" Presta valve tube
The least expensive way to ditch 40+ grams of rotating weight is with Specialized Turbo Pre-Talc'd tubes. A patented, oversized 4.8 cm valve base prevents tearing, while a partially threaded valve stem provides a clean interface with pumps. The 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.
