Brompton Tubolito 16 inch Schrader valve inner tube

Brompton Tubolito 16 inch Schrader valve inner tube

Tubolito make inner tubes with a difference. This inner tube weighs in at only 43g, which is a lot lighter (about 40g less) than many inner tubes. It is also about 2x stronger than standard inner tubes. The Tubolito inner tubes are also made in an environmentally friendly way

This was supplied with some Brompton P Line bikes where they were made with the C Line rims - to help reduce weight

The Tubolito inner tubes are made from TPU (thermoplastic urethane) which makes them lighter and more durable than standard inner tubes. 

The durability has been measured by a needle penetration test, this measures the force needed to penetrate the inner tube using a mandrel and the result was that they required twice the force to penetrate than a standard tube (this was MTB inner tubes).

The thermal resistance has been tested in accordance with DIN ISO 4210

They are orange - so you can spot them? No, this is to highlight the innovative nature of the inner tubes. 

The bonus as well is that they are environmentally friendly compared to standard inner tubes. The process used to make the TPU used less CO2 and water than standard manufacturing processes.  

The inner tube can be pumped up using a stand pump or a CO2 canister, the maximum pressure is dependent upon on your tyre choice and not the tubolito.

This inner comes with a Schrader / car type valve.

You should still check the tyre pressure monthly (for most tubes it's weekly). Running a tyre under inflated will mean that you need to put more effort into cycling and can result in damage to the tube / tyre or even the rim.

Repairing the tubolito inner tubes 

The tubolitos can be patched using the Tube-Flix-Kit. It is simple to use, with no separate glue, the tubolito Flix-Kit is provided with wipes to clean the area and patches. 

The tubolito inner tube fits ETRTO / ISO tyre sizes as shown below:
37-340 - 16 x 1 3/8" and 400 x 35A
28-349 - 16 x 1 1/8"
37-349 - 16 x 1 3/8"
28-355 - 18 x 1 1/8"
35-355 - 18 x 1.35"
35-349 - 16 x 1.35" 
(The ETRTO size is the most accurate way of selecting the correct inner tube and can be found on the side of the tyre) 

Q: What is the valve cap for?

The valve cap supplied with the tubolito inner tubes should be used, especially with Schrader / car type valves. It prevents dirt / water and chemicals from getting inside the valve and causing corrosion and damage - meaning the valve / tube will last longer.

Fitting of the tyre / inner tube:

We recommend against using tyre levers when installing a tyre and tube, as it can cause damage to the tyre / inner tube or both. It may seem difficult or even impossible at first - but it is just technique, practice and patience

We made the below video to show how to fit without the use of levers - with the toughest to fit tyre
