Folding bikes live on being light and compact, and so does the Tubo Folding. Tubolito makes it from TPU at 60% lighter than a standard butyl tube and two times stronger, a worthwhile upgrade whether you're riding the commute or carrying the bike up the station stairs.

Highlights

• 60% lighter than a standard butyl tube
• Two times stronger than conventional butyl
• Better air retention
• Small pack size makes it an easy spare
• Fits 20" tyres 1.2-1.8" wide, rim and disc brakes

Lighter to ride and to carry

Less tube weight means less rotating mass on the road and less to lift when the bike is folded. The Tubo Folding also packs down small enough to slip into a pocket or saddle bag as a spare.

TPU, not butyl

Tubolito makes its tubes from TPU, a high-tech plastic, using a patented manufacturing process. Tubolito tubes are TPU, so standard butyl patch kits won't bond to them. If you do puncture, repair it with Tubolito's own Tubo-Patch Kit.

Compatibility & fit

Fits 20" folding bike tyres 1.2-1.8" wide and suits both rim and disc brakes. Choose the valve that matches your rim: Presta (42mm) or Schrader (40mm). Many folding bikes use 16" wheels instead; this listing is the 20" size only, so check your tyre sidewall before ordering. Fitting is available as a separate Tune Cycles workshop service and is not included.
