As this subject continues to be discussed my guess (with over 25 yrs. Of riding tubulars and gluing all of them myself) is that the tire need to be aligned with the rim a little better. If the tubular is not flush with the concave surface on the rim there will be a small area of the rim where the tire will not have a tight contact which may cause a popping noise on each revolution. This can be done by putting about 20-30 in the tires after it is mounted. Spin the wheel and fined the wobbles. Grip the tire and by rotating/twisting the tire it will straighten out. Then air the tire up to 130-140 psi and let it sit overnight. I rarely prestretch my tires. I think that to glue well it is more about technique over strength. - the Conti Sprinter is a good enough tire that there is rarely a Sprinter with a wobble built into it. There is a very good chance that the seam tape if fine. Conti makes a very good tire (I prefer Vittoria , Torelli and a few others). On older tubulars this separation was a issue. Not with modern tubulars.

I just returned from a gloriously beautiful spring ride here in southern On tario, marred only by a squeaky front tubular. It's a Contintental Sprin ter, which I recently mounted on a newly built Fiamme Ergal rim. It was a chore getting the last bit over the rim--it appears I didn't pre-stretch it well enough. So there is a bit of a wobble.
Is this what is causing the squeak, or a problem with the gluing, or other?
Any help appreciated.
