Brompton Schwalbe Presta valve Inner tube 16 inch for T Line and P Line

Brompton Schwalbe presta valve Inner tube 16 inch for T Line

Supplied as shown - with no box - as supplied from Brompton

Note: This is for the T Line and the original (not very many were supplied) deep / aero rim P Line and current (as of 2026) P Line

If you have a C Line style rim with a Schrader valve then you should use a Schrader valve (e.g. AV4) inner tube

Note: This is actually the Schwalbe SV4 inner tube, but supplied by Brompton and not in a box, well sometimes it is the the SV4 box and sometimes not !

This tube has a Presta valve and is designed for use on the Brompton T Line and P Line which has a smaller hole (6mm) drilled into the rim (for this valve type) than a traditional Brompton which used an 8mm diameter valve hole in conjunction with a Schrader valve

This tube should not be used with a standard Brompton rim unless you use an adapter (as the valve hole on those rims is too big)

This inner tube fits ETRTO tyre sizes as shown below (not just Bromptons):

• 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"
