i wouldn't advise re-installing the tyre without any fresh glue, however,....unless the old glue is dried out, a light freshen-up application on rim & tyre is usually all that's necessary

Bump, finally getting around to gluing my first set of tubulars, this weekend! I have an old set of GP4 rims, well loved and used, the rear I just pulled the old tubular off of as I didn't trust it's condition, and I have a new set of Vittorias here.

Now for the question: how dry is too dry to let old glue remain in the rim without stripping it down? The rear wheel hasn't had a tire on it in a while, but the glue is still tacky to the touch. Enough to make the carpet or a towel stick to it if left for any length of time. Front wheel is much the same, had to use a reasonable amount of force to pull the old tire off. Should just a light coat of new glue on the rim be sufficient?

Yes, light coat is good.

Tacky is still usable. Dry & crispy - no.

Cool. I'll hopefully have a road worthy set by the end of the weekend. Get a few miles on them next week in the evenings on my after-work rides.

Great thread! I am looking forward to applying the techniques discussed here. I just ordered a set of NOS Campy Victory Stradas to mate to my Chorus hubs. These will be mounted on a '86ish Eddy Merckx Corsa Extra. I am thinking of going with Veloflex Criterium tires. Anyone have opinions on them good, bad, or otherwise? Thanks.

everything i've heard about them indicates they are awesome.

I've been using a set for a year on my Waterford and love them! They are worth every penny. got mine from critusa@aol.com Danny has them at a good price and free shipping.

I have a pair of silk tubulars that are for display only, not riding. The silk casing in one spot is not in very good condition. Two questions: 1) Is it possible to repair that area, and, if so, with what? 2) Is there a way to remove the old, darkened latex from the sidewalls without damaging the casing?

I Think liquid latex will clear up any problems with the 2nd tire show.
Jevelot Tire Life is the product I've always used.

as for cleaning them up? I'd not mess with anything that could remove
the old latex to clean it up.

Excellent! Thanks very much, Marty.

I agree with the Jevelot Tire Life. I would especially not touch the sidewalls with anything that could catch on a thread or otherwise abrade and weaken a thread. I made this mistake with a collectible and otherwise usable original Italian Vittoria CG Servizio Corse, and the tube herniated through the weakened portion of the sidewall while riding. Didn't fall, but I lost a good tire due to carelessness.

Bottom line is, don't clean off the old stuff, cover it up with latex, in my opinion.

Thanks, Road Fan. That's kind of what I figured. I had hoped there was a product (mineral spirits?) to remove that ugly latex without harming the silk. Unlike you, I won't be riding these (display only). Anyway, I will buy some Tire Life so I can repair the spot shown in the first photo.

Any remedy for a lump? Developed in the last 15 miles of a 45-miler today.

None that I have ever heard of. The casing is shot.

yup: take it off and throw it away, and put a new one on. quick, before it pops on you.

That's what I figured. Any recommendations on something befitting a '74 Masi Gran Crit? Veloflex or Challenge Criteriums maybe?

Both are good choices. How about Andre Dugast?

No doubt. I'll have to ask Santa if I've been that nice this year.

how puncture-resistant are the veloflex offerings?

or, can anyone recommend a quality durable/puncture-resistant tubular tire with a tan sidewall?

also, I read that one should leave two inches or so of an unglued area on the rim so that removal of the tire can be done with ease. is this recommended or a common practice? I read this here: http://davesbikeblog.blogspot.com/20...re-to-rim.html

thanks

Clemente Criterium Seta, as long as we're talking big bucks.

I havent' tried this method yet, but I plan to next time I install road tires. I can't see any reason why just leaving a few inches free would make any difference to tire retention. I would definitely consider it safe.

Having rolled what I thought was a well-glued tubular before, I would personally not use that method. Glue the whole thing.

Out of curiosity, what glues are you guys using? I've only been able to fine Continental glue, which is pretty good, so no complaints. I used to use Clement white BITD, and Clement Red for the track, but of course Clement is no more (except for the very small stock of Campionato del Mundo's in my basement).

Also, how are Dugast tires? I'm mainly interested in the Paris Roubaix 27mm cotton's for my "Sunday wheels", for the day when my CdM's have ridden their last ride.

Thanks

What is wrong with it? the hump or the discoloration? I don't know that well the meaning of the word lump and the dictionary is quite vague.

If the problem it is the hump, it is super clear to me that the tubular it is not in the right position. Look at the valve. Take the tubular off the rim and re glue it. Done.

I see that apparently you got a flat right there nearby the valve stem. If that is part of your problem, just unsew it (the sew up got saw), and sew up that part of the tubular really well (15 minutes as much).

If the problem it is the discoloration and dryness in the lateral walls of the tubular, thats because the tubular is simply old. I have used even older tubulars, you shouldnt have a problem unless the road band is pretty old too.

Thanks.

It can be done even smaller hehehe... old timer in here.
