The Sunlite Utili-T Bulk Thorn Resistant Schrader Tube Box is built for shops, agencies, fleet programs, and service departments that need high-volume thorn-resistant replacement tubes. These tubes are bulk packaged and sold as a box of 20.
Each variant uses a smooth 48mm Schrader valve with a removable core and 3.7mm / 1.7mm thorn-resistant wall construction for added puncture protection. This group covers common 20 inch, 24 inch, 26 inch, 29 inch, and 700c tire sizes used on mountain, utility, cruiser, commuter, and fleet bicycles.
