Just after I got my T-Line, I went to the Brompton shop in Covent Garden and asked to buy some spare inner tubes. They recommended that I didn't buy Tubilitos and not long afterwards, I realised why. It turns out, however, that the tubes they sold me might be more puncture resilient than Tubilitos but they are not Presta valved and so a pleasant couple of hours spent seaching for Presta valved Brompton inner tubes took me to a few local bike shops.
Got there in the end.
Anyway, I now have plenty of spare inner tubes for my C-Line.
