A bit more information: I was riding tubulars in Italy during the summer.
I was doing quite a lot of longish climbs and descents - something that I am not really used to, living in Belgium.
I thought the problem might therefor be because of braking too much, which
could overheat the rims and thus melt the glue on the base tape. Would be interesting to know if others have come across this problem - it doesn't seem
to be a common one, otherwise I am sure it'd have come up before.
Cheers,
Johnny
