Have your tubulars ever made noise when you ride them?

Have your tubulars ever made noise when you ride them?
I had LBS glue my new wheels, the first tubulars I've owned. The front one makes a noise once per revolution; if I sit upright and hold the bar tops, putting most of my weight on the rear wheel, the noise gets quieter or goes away.
The guy at LBS says occasionally tubulars make a noise, because the bottom of the valve is flat instead of rounded. He said it may or may not go away as the glue dries, and it didn't. This mechanic has always done excellent work and seems very knowledgeable, but this seems weird to me. Also, as best I can tell (it was dark by the time I got to ride) the noise starts when the valve is toward the top of the rotation, not when it's at the bottom. It's definitely not the brake.
It's hard to describe, but kind of a psssst! sound. At first I thought it sounded like going over a patch of sand, but it's probably more like pulling glue. Anyway, I'm worried that something might be wrong, like maybe the back of the valve is grinding into the rim? I'm using Zipp tires made by Vittoria (supposedly Corsicas with a different tread pattern) and put 110 psi in them, if that matters, and I've put all of 10 to 15 miles on them.

had the same problem with my vittorias. I noticed that when the valve would reach bottom it would make the same noise... at first I thought it was when it was at the top... but it was just spinning too fast to really notice. This didn't happen on my continentals, just the vittorias. I think it is because the valve stem is so light weight and mine were the 80mm stems so they were pretty long too. When I tucked a thin sliver of old tube down the side of the valve to wedge it, the sound went away. I ran 110f 120r if it makes a difference.
Hope this helps

The last noise my tubulars made was BANG! twhup thwup thwup.
Seriously, I did have one make the noise you describe, it had a tiny piece of debris in it, every revolution it would poke into the tube and let a little more air out.

I have not had any strange sounds on either set of my tubular wheels, but I do like the road noise the deeper ones pick up, AWESOME! I say ride and enjoy.

Does it sound kinda like pulling a piece of tape off of something? If it sounds something like that, it means that the glue didn't adhere to the surface and its pulling...if that makes any sense.
I had to pull off the tire and re-glue.

Vittorias are known for this. I think it's an air pocket and it makes almost like a squishing sound. It means that somewhere in the gluing there is a spot that is not fully glued and a little air is trapped in there. That is why when I glue I inflate the tire, roll it up and down my driveway, deflate and press the tire into the rim with my finger or broom handle, then reinflate to let dry.
I would check if they could reglue it for you.

Even if it was the valve the glue should be dry and not make noise.
Have you had a chance to examine the wheel in better light?
If I've had noise it's because a bit of a leaf or something got stuck on some excess glue and rubbed something.
To check the glue job you should check the edges. There's a good article in VN about that.

Also, a pair of posts on gluing and removing tubulars. The removing part is key - it should be extremely difficult.

And thoughts on rolling a tubular, i.e. what happens when they roll.

Thanks, everyone. Sounds like I need to bring it back and see if they'll reglue it. Bummer.

I had same issue as poster 2. If you dont glue the valve perfectly perpendicular, it will knock against the valvehole in the rim. I used a little electrical tape around the hole there, took it away.
it was more noticable when I rode the wheels vs the wifey (more weight). I would check it out as you do mention that shifting weight on/off front/rear wheel makes a difference....

I have a question after reading this since I had planned on gluing my own tires when the time comes: If you glue tires and have a small spot, like suggested, that does not adhere properly and is making the noise described, do you have to re glue? Is this a sign that the tire will eventually roll off or will the tire most likely be fine to ride? What is the best way to ensure aa good job has been done? I know there is plenty of info out there, but it is easier to ask here since experienced people are already posting.
