Clement was my favourite at home and in the shop. I never had or knew of one that failed, but I know it can happen. You needed to be like Merckx and dump water on your tires as you descended! When I was at the US Olympic Training Center in about 1989, they used a 3M product which I think was used for automotive trim--- somethingbond. It did fail more than once and the one time I was able to see the tubi afterward the adhesive had failed cleanly, staying with the tire but none of it remained on the rim.
