Brompton 16 inch Inner tube - by IMPAC

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

Since 2019 this has tube has been made for Brompton by IMPAC (a part of Schwalbe tyres) 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: No

In 2019 Brompton changed from a Kenda made tube to an IMPAC (a subsidiary of Schwalbe) made inner tube. The dimensions remain the same (the tube is slightly lighter than its predecessor)

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)
