Tubolito Tubo Road 700 x 18-28mm Tube - 42mm Presta Valve

A TPU road inner tube for 700c tires from 18 to 28mm, the Tubolito Tubo Road is built for road and all-road riders who want roughly half the weight of a butyl tube without committing to the disc-only S-Tubo. Tubolito lists the weight at 38g, with roughly twice the puncture resistance of standard butyl per their testing, and the packed size drops small enough to share a jersey pocket with a multi-tool and CO2 head.

The 42mm Presta valve covers standard rim depths, and compatibility runs across both rim and disc brake systems. Note that flats require Tubolito's TPU-specific Tubo-Patch kit, since butyl patches will not bond to the material.
