Re-Glue Tubulars?(9 posts)

Re-Glue Tubulars?Wayne

With cyclocross season fast approaching I want some opinions. I got a set of Heliums at the end of the '01 season and glued some Tufo's on. So they saw a handful of races at the end '01 and then a full season last year. So is it a good idea to re-glue them or is this a case of if it ain't broke don't fix it?

Normally, I would recommend regluing tubulars every season. I live and ride in Texas and the heat does dry out the glue. However, I had such bad luck with the Tufos last season that I wouldn't do anything to them that might disturb the valvestem. I had 4 Tufos from 2 different shops that started to leak where the valvestem enters the tire. The tires started out round and straight but after a while seemed to squirm a little and in one case, I could hear the valvestem clicking as it moved back and forth inside of the hole in the rim. I have suspected it might be the Tufo sealant in the tire softening the glue they used to hold the valvestem in the tire.

I always reglue before each season. Some might recommend reglueing more often than that, but I would definetly reglue them if I was you!

I deflate (or inflate) mine just enough to have some shape, and then I try to push the tire off the rim. If it comes off easily, reglue. If it is difficult, it's probably ok. If the glue appears to be dry, flakey, or makes a noise while riding, reglue.

I've found that some glue-jobs are pretty darn good and can easily be ok for over a year. The existing glue-job might well be better than the one you might re-do.

I don't think there is any reason to arbitrarily re-glue; test it first.

... my glue method requires 3 coats of glue and about 3 days to set up before a ride (Vittoria Mastik One exclusively)... and as such, on one wheelset, have held up well for nearly two seasons (stored in doors in dry, cool basement). I test 'em per Doug's abovementioned method... and this has worked well (which is kind of a drag... I've been eager to try tubular glue tape... but I've got a new wheelset coming... so I'll try it then).

The only glueups that I might change outright are those done by other folks (bought a slighly used wheelset with one tubular mounted... it gets yanked and reglued at the end of season at best).

just slap some glue on, let it sit for 15 minutes, then put the tire on. Shheesh!! Some guys make tubular mounting a religious experience!
If your really in a hurry, spin the rim, and put a glob of glue on the end of a 3/4" paintbrush. touch lightly. wait 10 minutes, mount. clean up mess later. Hey, it works, and i've never rolled a tire, either.

Yes, it does work. It took me a while to realize that I am not gluing stress memebers on the Brooklyn bridge. The cement is good. The tire holds, and, if you flat, you can actually *get it off*. With three coats of Clement, there was no way you could get the tire off, except with a lot of cursing.

... can't deny anyone else's methods if they work for them... as for me, I'm too old to keep getting up after a fall and yep, too anal to change...

The very nature of most contact cements is to allow time for volatile solvents to evaporate... thus three thin coats with time allowed for drying... ensuring better overall retention.

As for the method itself... adhereing to (no pun intended) said, assures me that I've done a consistent job of glueup... and if something were to go wrong... I might be able to eliminate a couple of possiblites (consider it a pre flight check list... boring... until the $hit hits the fan) rather than questioning the entire process.

Besides, I thought cycling was a religion (was in church for six hours on Sunday)...

You are right. One of the difficulties I had, as I said, was getting a flatted tube off the rim. A thin coat seemed to be okay, and I could get the tire off :-). But going down a long, curvy, steep grade in 95 degree temps, which is common for me, makes me think about the glue on the rims. "Richard's Bicycle Book" recommended gluing both the rim and tire, letting it dry, then gluing the rim and doing a wet mount. Mounting when the glue is wet is, er... tougher to do. I realized that you can let the glue set up and just mount the tire, and that was fine for training.
Also the glue differed. What was the red death? Was that Clement? Gawd, you can't get that stuff off :-).
I liked Panaracer glue, but it really stunk.
