Hello everyone, new user here just wanting a bit of advice.
I have a Brompton which I have been riding infrequently for ten years or so. I have Schwalbe tyres and tubes, but I always find them down on pressure when I come to use the bike (sometimes after a few weeks), and have to top them up (which I do by judgement, not to a specific pressure). I am quite hefty (107kg) so I do run them at high pressure, perhaps over spec (I inflate them till they hold shape when I am sitting on the bike), but I have not had this problem with other bikes. Can anyone suggest a different tube option which might hold the pressure better? Perhaps the problem is that my weight is all on the back wheel which is small, whereas on another bike the weight is spread over two larger wheels...
EDIT: Just wondered if trying a presta valve instead of the car type would be worthwhile??
