Due to its very small packed size the S-Tubo CX/Gravel is the ideal spare tube for all 700c and 650B tires from 30mm-47mm. However, not only can it be used as a spare, but it can also be used on a daily basis as it still is as robust as standard rubber tube. Disc brake compatible and also compatible with any sealant left over in a tubeless tire. Not compatible with rim brakes.
