Double Checking a glue job on tubulars.(11 posts)

Double Checking a glue job on tubulars.niteschaos

How do I know if the tire is properly glued to the rim? I inflated to 130psi after the tire cured (the pressure I plan to ride on) and tried to move the tire, but I couldn't get it to do anything more than flex. As far as amount goes I used a whole tube of glue on each wheel.
Holy Sh!t! A WHOLE tube?????!!!!Alexx

Those tubes are good for 2 tires, maybe 3, if you are doing a re-glue. I'd bet that all that excess glue is going to be gumming up all sorts of stuff, if it isn't all over the braking surfaces by now..... Bet you glued around the valve, too, huh?
BTW, what brand of glue did you use?
How did your comment answer my question?niteschaos

I used Hutchinson. About half of the glue was used on just the base tap of each tire. And no...there isn't a gluey mess. I'm surprised how well they came out, cause glueing was simpler and easier than it had be described to me and I didn't get glue anywhere but between the base tape and the rim. These were new tires and new rims.

Again, your comment didn't answer anything on double checking the quality of the bond between base tape and rim, other than inflating the tire and trying to roll it off the rim myself by hand.

This guy is a knucklehead. He's the same guy that claims to carry a supply of pre-glued tubulars in plastic bags when he rides. Come on. Nobody and I mean NOBODY carries glued tubular tires with them but this guy. Hey genius, here's a clue--- they make these things called clinchers that use inner tubes. So with that in mind it is easy to see why this moron would only use the bare minimum amount of glue to hold his tire on. He has to use his buggy whip arms to pull the glued tire off the rim and then reinstalls a freshly glued tire and you don't want a lot of glue for that.

Oh yeah, to answer your question, I always use a whole tube for each wheel and like a later post states don't really worry about checking it if the inflated tire doesn't move you are okay. Please don't tell me that you carry glued tires with you on rides too.

I can see a fresh tire and rim combo using close to a full tube of glue if applied on the heavy side. Sounds like he did a good job of applying a base layer to both the tire and rim before mounting - but I agree, deflate to verify. I do have to disagree that NOBODY carries a pre glued tubular along - I, along with two others that I know carry a spare tubular along for the ride. I just can't see riding 50+ miles away from home without the ability to fix one flat.
So to confirm the test method...niteschaos

Deflate to 30psi and try to move tire while listening to cracking of the glue bond. Thanks guys.
and carry a Tufo glue strip for the spare nmDougSloan

In case this is a news flash for you.....tubulars hold best with just a LITTLE glue. It cures faster, and forms a stronger bond if there is just a thin layer. Put a lake of glue between your base tape and rim, well..., I guess we know who's more likely to roll a tire off.
deflate and try to removeDougSloan

Deflate them to about 30 psi. Then, use your thumbs to try to roll the tires off the rims. If you can cause them to pull up at all, they are probably not glued well. It should be fairly difficult to peel them up.

The most important part of the glue job is the outer part of the tire, next to the edges of the rim. Make sure the glue goes all the way out.

Also, if it ever appears to be cracking or drying out, re-glue. If the base tape is pulling from the tire, as it might when it gets old or after removing the tire from a glued rim, either re-latex the base tape or replace the tire.

I had great success with Tufo glue strips. They make it almost foolproof.

Don't worry about the amount of glue you used. If the base tape wasn't latex coated it's easy to use a half tube or more just priming the tape. To check the tubular mounting, just press on the side of the inflated tire with your thumbs and see if it moves or "crackles". If so you should re-glue it.

Yes, you probably used too much glue but this is a learning process. I usually get 2 new tires or 3 reglues out of a tube of Conti. Don't take the negative comments seriously. Consider the source and most of them are trying to decrease your self estime to their level. If they can't or aren't willing to try what you are able to do, then they will try to tear down your efforts. Hang in there and enjoy your abilities and learn from your efforts.
