I've had my tubies on for about a year. I'd like to take them off and re-glue them.
Was wondering if anyone out there would be kind enough to provide me wiith instructions since I am not sure about the difference between gluing a tubie on for the first time and pulling the tubie off and re-applying glue.

Thanks in advance for your help.

Perhaps instead of just flaming me for such an egregious error; using the term "tubies", you could have answered the question. But I guess your arrognace got in the way.

I commend you for being proactive with the gluing.

*edit* other than removing old glue from the rim, and stretching a new tire, not much difference between regluing and gluing.

Ahh, singles.

I sure don't miss the bastards... wait, I do.

...No, I don't.

I had em on a bike I used for transport. Silly.

Could never manage to get em stretched on evenly enough not to have a bit of runout happening.

But damn, they stuck to the road... and felt like they had 20psi less in em.

Don't bother removing them, if the glue is holding.

Tubular glue for track use are not designed permit tires to be taken off easily.

Tubular glue for road use is designed to be removed easily. Hopefully, the glue is still tacky. You probably will not need to spread a new layer of glue on the tubular, just the rim.

If they are properly glued, and only 1 year old, I wouldn't mess with taking it off and regluing. If it was glued correctly, you are going to have trouble getting it off and possibly damaging the tire. The rim strip tends to come off, which complicates things.

Tires need to be reglued becaue the glue becomes very brittle, which usually takes quite a while, but depends on the brand of glue. Just poke a bit of the glue that has oozed out from underthe tire with a fingernail to check for brittleness.

The main maintenece to do with a sew up is to check it often to make sure it is stuck. Lower the pressure so that the tire just holds its form (around 30-40 psi), grab a section of tire with both hands, thumbs under the rim and fingers on the tire, and roll your hands away from you as hard as you can. The tire should stay put completely. If it starts to come off, then definitely reglue, otherwise, leave it.

You don't have to re-glue sprints unless there's reason to think the current glue is failing. If the tire does lift or roll easily off the rim you'll be fine.

The tire became deflated, and I think that there may a problem with the valve. Won't be able to tell until I pull the tire. The tubulars are on Zipp 400's and therefore have extenders.

I promised myself that, when I do pull the tire, I'm going to get extenders that can mate with the valve externally instead of leaving it buried inside the rim. So I guesss I can use this as an excuse to do just that.

Well, "Tubs" doesn't sound that great or seem to make any sense either............I'll just start calling them "tubulars" myself............

you can only call them 'tubs' if you have a deep Belgian accent. talking about 'tubies' may cause some younger members to think you are doing something with the telly tubies LOL

I too have never heard of just removing them for the sake of routine regluing.

Isn't there a notion or logic out there that you'll wear out the tubular tire first or possibly get a flat that needs "invasive surgical" repair before ever needing to do any regluing becuase of aged glue??

I just pulled one off of a wheel that looks like it's been in storage for years and the glue was still sticky.

Can't say - how good are you at steering around the broken glass?

I think the glue gets brittle if air gets to it too much.
I spent quite a bit of time removing really hard and brittle glue residue (it was like violin bow resin!) from the otherwise mint GL330 wheelset I aquired last fall, a wheelset that had been hanging for many years with tires unmounted to it and the old glue exposed to the air in the back end of an LBS. Some questioned my efforts on cleaning it off, but i really didn't want to think that some of that hard brittle glue might affect the adherance of my tubular tire in the future.....plus I'm kinda "anal" about many things as I suspect most C&Vers are anyway......

I think I'm OK, I don't remember ever getting a flat from glass on the road. All I can remember from years riding HP clinchers are snake bites, pinch flats and pot hole caused blowouts/tears. I hope my luck holds out with tubulars....

There's an unfortunate fact about tubulars. They get flats just like other tires. When they get a flat you will have an opportunity to re-glue them. Until then, don't bother.

The tire is flat and not holding air. I have a suspiscion that it might be the valve, but the vave is buried inside Zipp 404's wiht only the extender protruding. I am probbly going to change the extenders to those that have the valve placed on the top. And yes, I probalby should have mentioned that in my original posting; sorry.

Anyway, reealizing that there is a risk to the tire, and I'd rather not have to remove it, what is the best way to go about this, aside from the obvious .... being careful.
