I noticed that there are some fans of Clement red. My understanding is that Clement red is usually quite good - but we've had some over the years that was simply evil.
We would to the glue on base tape, bunch of glue on rim thing. And then a final thin coat and quickly put the tire on. The tire would then, for a couple of days, feel as well glued as anyone could imagine. Seemed like a job well done!
Wrong - another couple of days later, give the tire a hard tug, and the tire would pull cleanly off the base tape! Very little if any would stick to the tire base tape at all!
The culprit our wise guru Paul LeMaire told us, was that the batch of Clement tires we were using had the base tape impregnated with something that repelled the glue! Other glues worked fine on these tires, but not Clement. (Vittoria red or clear worked like a charm). Also, the Clement glue, if I recall, might have worked OK with other brands of tires, but I'm not sure.
Now, one is supposed to prep the tire base tape prior to gluing, but in practice this seems to be rarely necessary (we tend to get our tires glued on too hard if anything so we're doing something right).
The upshot is that at least the batch of Clement red we were using would not stick like other glues. We couldn't sell the stuff when we discovered that, and we simply put the remaining inventory in the trash.
To make a long story short, if you use Clement red test the tire really hard everyday for quite a few days (before each ride is a good idea) to make sure you don't have some of the evil red.
These days we simply use Vittoria clear (the Mastik one stuff) and are very happy. And yes, tires can creep. The best we can advise is to be sure to use both front and rear brakes evenly and try, if posible, to work on cornering technique so you need less braking (a big deal here in Boulder with the mountains).
If it all seems like too much of a hassle, try some of the sweet clinchers on the market. We're using them more and more and are even feeling less guilty about admitting it.
