Inner Tubes 20 to 36" (Nimbus/FOSS)

As low as £18.00
58% of 100

We have had a totally new type of tube that we commissioned FOSS to produce for us.

The problem with the big wheels is that the inner tubes weigh a ton! This diminishes the performance of the tyre and hence the unicycle.

Made from modified thermoplastic elastomer compounds (TPE), EFT can be recycled with other TPE products protecting the environment by minimizing waste.


We can supply a correctly sized light weight tube. These tubes are made by FOSS and they have taken the mountain bike world by storm. Not only are they light but they have self sealing properties for thorns and other intrusions and can be thermally repaired (we have seen this done with a lighter).

The supplied tube may not have the clear appearance shown in the pictures, if it is not Clear it will be blue.

Valve: Schrader
Material: EFT - highly polymerized un-vulcanized rubber composite. When punctured, the material forms an air-tight seal retarding the leak speed giving the rider extra time to make safe repairs.
Elasticity: The elasticity of EFT make them resistant to explosion and pinches providing added safety for riders.
Weight: 185g (29"), 214g (32"), 239g (36") (weights are +/- 5g) (can be 30% lighter than traditional tubes)
Size: 29", 32", 36" x 1.95 - 2.25"

Note: You have to use the Foss repair patches with these tubes (standard patches don't work)
