Tubolito S-TUBO MTB Disc Brake TPU Presta Valve Inner Tube : 27.5"x1.8-2.4"

Inner tubes are old hat in the cycling world: they've remained largely unchanged for decades. However, the fine folks at Tubolito have gone out of their way to update the most overlooked part of a bicycle. Made from a unique thermoplastic polyurethane, the Tubolito S-Tubo-MTB are a featherweight inner tube built exclusively for disc brake use. Without having to worry about the effects of rim brake friction on the innertube, Tubolito was able to lighten them up even further, down to a mere 45 grams per tube (29"). Due to a removable valve, S-Tubo-MTB's can be rolled up to an extremely space saving size (Ø 3.5 x 5 cm). Despite their light weight and small pack size, the S-Tubo-MTB feature the same puncture resistance as your standard rubber tube.
