@hippy there's some chat about the tubolitos in the TCR FB group, some have had success, others have had lots of flats and leaking valves. I've used one and had a flat quickly, but that was probably because the tyre was so worn out you could see the casing. Kim was using those too for a winter a year or two ago, didn't have problems as far as I know.
