So I got a flat on my t line (tpu tube) but such a small flat it takes like ages to deflate but anyway I can’t use a spare schrader valve since my wheels only accept presta but Brompton don’t sell non Turbolito presta inner tubes?
Any suggestions?
Thanks

A massive range of TPU tubes is available via AliExpress. The stem/tube interface is generally the weak point on TPU tubes, but leaking non-replaceable cores seems to be a problem, as well. [Here’s a test of a bunch](https://www.youtube.com/watch?v=xPx8K0IdqRU) of them.
Both Continental and Schwable make Brompton inner tubes with Presta, you can just Google “Brompton presta inner tube” not difficult to find.
I use just the standard Schwalbe presta valve tubes on my T.
I use ridenow tpu tubes with alloy stems

Schwalbe SV4 are Presta tubes for 349. Kenda make some and other no name companies if you want to go butyl.
