I've just had an excellent summer getting back into more serious bicycle riding.

Warning on some clincher tires and HED rims

re:Rim strips: a cautionary tale
In category Tech issues
Written by lapierre

First off, of course I should know better. But the caonsequences were mild and I take the following as a learning experience.

For many years I've used a couple of layers of fiberglass strapping tape if a real rim strip was not handy. Until today, I've never had a problem. Today this could have had catastrophic consequences; but I got lucky.
