TUBE SPECIALIZED PRESTA 700X20-26 40MM

Specialized tube Turbo Presta valve 40mm 700x20-26. Specialized product code: 03019-0200. The least expensive way to ditch 40+ grams of rotating weight is with our Turbo Talc Tubes. A patented, oversized 4.8cm valve base prevents tearing, while a partially threaded valve stem provides a clean interface with pumps. Our 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.
