This inner tube has a Presta valve, so it's suitable for T Line Bromptons - most other Bromptons will use Schrader valves.
Of all the places to save weight on a Brompton, the wheels make the most noticeable difference.
Standard Schwalbe inner tubes come in at approx 85 grams, and the Tubolito tubes 43grams. Running a pair drops all important rotating weight and helps with acceleration.
If you are packing a spare they are also about physically half the size of a standard tube and much easier to pack.
Prompt weight savings: using Tubolito can make folding bikes instantly lighter, so they can be carried along easier.
Due to the processing of new materials the production of Tubolito tubes needs much fewer water and emits less CO2 as the production of tubes made of rubber or latex. This makes Tubolito a very ecofriendly inner tube.
Tubes can be patched and repaired but only with the special Tubolito patch kit.
