Brompton 16 inch Inner tube

This 16 inch inner tube is supplied as shown - with no box - as supplied to us from Brompton

Since 2019 this has been an IMPAC manufactured tube as shown in the lead picture

Note: From 2012 the Marathon supplied by Brompton and the Marathon Plus tyre are no longer 16 x 1 3/8 inches or 37-349, but 16 x 1.35 inches or 35-349 (slightly narrower). For the narrower tyres you should use the Schwalbe AV4 (which is suitable for both versions) or the QTUBXL (please see the accessories tab) - it will fit inside easier

Brompton / IMPAC 16 inch inner tube specification:

Inner tube weight: 97g (according to our Park Tool scales and with a sample size of 1)
Rim nut: NO
Valve cap: Black
Removeable valve core: ?

In 2019 Brompton changed from a Kenda made tube to an IMPAC (a subsidiary of Schwalbe) made inner tube

From 2013-2019 this was a Kenda manufactured tube - this is still shown in some of the historical pictures

Valve type: Schrader / Car / Auto / American - 8mm diameter

Note: We suggest against using tyre levers when installing inner tubes and tyres to your Brompton. Although the tyre fitting may seem tricky, it's just technique to do it tool free - see the below videos for help. (Using tyre levers can often result in damage to the inner tube - pinching it when installing, or to the tyre bead, or both)

The below videos from Brompton may be helpful in seeing the technique for installing your inner tube (and wheel removal / installation):

Very happy with my order! And great service. Thank you!


    Excellent service

    Brompton inner tubes are not that easy to come by, so I was very pleased to find Brilliant Bikes.
    Order came very promptly, so I am well pleased.


      Fantastic value

      In a mad fit of incompetence I called in to my local H******s for a tube. They tried to sell me their fatter tubes which their manager insisted would fit a Brompton. As a wary person I refused this and went online. This is where I found this site. A perfect sized tube complete with useful info. I thought I should buy two for spares but seeing the free delivery my meanness took over and I only bought one. Delivery was next day - should have bought two but anything else from my Brompton will be bought from here. You won't get rich from me because I've had this bike for years and nothing ever goes wrong.


        Great service

        Was having trouble finding this item in stock elewhere but once ordered here it went through like greased lightening and arrived first thing the following morning. Brilliant; will definitely use Briilaint Bikes again

            I would like to know if this is the right inner tube for my brompton b75 . My front tyre had a puncture and i went to halfords and they told me that they don’t have the correct tube for brompton . I ordered before an inner tube from you guys the brand is schwalbe. Supposedly it’s compatible for brompton but the guy in Halfords told me that there is another one . I think this is what they were talking about. Answer:
            This inner tube is made for Brompton by Impac, a subsidiary of Schwalbe. We think it is identical to the AV4 made by Schwalbe (link as follows:, just without the rim nut. The tubes made by Impac are used in the Brompton factory and we understand that the lack of rim nut are them quicker to instal! Hope this helps and let us know if you have more questions.
