Tubolito S-Tubo MTB Spare Tube

Article number: 01-05-05

Tubolito Tubo tubes are between 2 and 3 times lighter than standard butyl tubes, while being twice as strong and half the packed size. With their new S-Tubo MTB line, Tubolito takes the weight savings and packability even further, cutting approximately half of the weight off their already incredibly lightweight standard offerings.  While their 29er Tubo tube weighs in at an incredibly light 81 grams, the S-Tubo version comes in at a shockingly light 44 grams (about 80% lighter than a standard butyl tube)! Not only ultra-lightweight, the packed size of these tubes is minuscule; measuring a scant 1.4” (3.5 cm) in diameter and 2” (5 cm) in length, these already tiny tubes also feature a removable valve to ensure the smallest packed size possible.

While the S-Tubos can be used as an everyday tube, we recommend the Tubo line for this purpose with the S-Tubo as an ideal ultra-packable and ultra-lightweight carry-along spare.  Sealant will not work to seal holes in the Tubolito tubes. However, contact with sealant will not harm these tubes, making them a great “just in case” spare for tubeless set-ups.

Available in 27.5” (650B) x 1.8–2.5” and 29” x 1.8–2.5” and includes a small valve installation tool and a 42mm replaceable Presta Valve.
