I can't imagine I will every be both so unlucky and lucky at the same time with tubulars.

My roadside routine for two decades was to carry either new spares or previously glued and ridden. New for a nice, tight fit or pre-ridden for the glue-like tape surface that didn't stick itself together too badly (plus I used the Diablo Scott folding technique that I learned in 1975. Did you you get royalty payment?)
Now I glued with Tubasti that keeps a good stick after the tire is pulled; assuming there is good adhesion to the rim. I only used hard glues on race wheels and did tire changes from the follow van. (That is a really good, quick, and clean hands system. ) I did treat my spare on old glue gently at least for the first mile or so and didn't pull race corners until I'd re-glued after I got home. And made a point of judging both spare and rim glue condition. Pumped to the hard side. Rode accordingly. And usually found I had to do some work to get the spare off. (Many old coats of glue is very good here!)

It's really the legacy I'll be leaving behind that matters most to me.

A week ago I was riding my Bianchi and got a flat. Had to use my spare (it was old and in bad shape) was about a mile from home and BOOM, full sidewall blowout of the spare. Choices..... Ride home on the flat spare. Walk home. I happened to be about 200 yards from CapnJohnny's house. So I coasted there, he leant me a spare, and I road home.
I can't imagine I will every be both so unlucky and lucky at the same time with tubulars.

I normally just display my leather bag projects in the DYI Bag Making Thread, but it is appropriate to post here since we are talking about spare tubulars, etc.
I call it the "Tubular Lunch Box" and it holds two cans of Vittoria Pit Stop, a Schwalbe One 27mm tubular folded the @DiabloScott method, and a fresh roll of effetto Mariposa Carogna Tubular Tape.
I designed it to mount under two handlebar mounted water bottle cages on my '71 Paramount P13 (but it can double as a saddle bag. The Paramount is not currently ready for a photo-op.

My LBS just did me a solid! After spending way too much time net shopping for Conti cement either in can or tube, I went by my LBS to see if they'd give me a bulk deal on the tubes, and the head mech sold me a 12pk of tubes for an unexpectedly low $30. One more ongoing annoyance in the done basket.

Question:
When you have two nice wheel sets -- one clincher and one tubular that go with your weekend 50 mile local ride nice bike, which wheel set to you choose under the following conditions?
Currently wet roads, fog, mist, and light rain likely for the rest of the day.
When it's wet, I take the clinchers. How about you?

Yes. I bring along a spare roll of tape - fits in the saddle bag easily. Knock on wood, I've not had to put it to use out in the wild yet, but I'm ready to give it a go should the opportunity (misfortune?) arise.
Apologies for the late reply; been AFBF for a minute.

And my clinchers are on my summer/fast/light weight bike and the tires are light weight 25mm and they never get wet and that bike never gets dirty.

I sure can! Though I was quite lucky in that it was only 3 miles, and I was wearing flat-soled touring shoes.
Still and all, that 3 mile walk was preferable to the 15+ miles I was obliged to ride standing up after the carbon shell of my Flite Evo filed for a divorce from the saddle rails

From what I've heard from others, Stan's is a kind of stop-gap (particularly with latex tubes - which are encased within my current pair of Vittoria Corsa Control G+ tubs). Because others' reports of Stan's tendency to lump up over time after using it in latex tubes, I'm on the fence. Full disclosure: I have yet to use it myself; I'm being wary going this route simply based upon anecdotal evidence. Could be it works fine in the long run - but I have seen a photo or two of tubes treated with sealant. They ended up resembling link sausage when the sealant dried in clumps!

Here are a few things I've learned about preparing tubulars for installation in the past 6-7 months.
When you get them, inflate them to about 40 psi - don't mount them on anything yet.
After a few days (maybe a week), deflate, and mount them on a rim (no glue), and inflate to about 40 psi again.
After another week (although it might be best to just leave them stretched over the rim until you want to glue them), they should be nicely stretched, and quite a bit easier to manage when you do go to glue them on.
Also, a few days before you want to glue them on, put a layer of adhesive onto the rim(s) you're going to mount the tire(s) to.
Unless you're dealing with really old tubulars, I suggest using 3-M Fast Tack for glue. I must say though that I've heard that Fast-Tack can cause the base tape on older tubulars to separate from the tires. I had a pair of old Wolbers that this happened with, but I haven't had it happen on any of the other tires I've used. Anyhow, here's a technique that I've used to mount tires with very little mess. I don't ride very aggressively, so I haven't ridden on any hairy, high-speed descents, so I can't vouch for how this holds under those conditions.
Before you start, have some mineral spirits and a clean cloth rag at hand. Sit in a plastic chair in a clean well ventilated space, and put on vinyl or latex gloves - the very thin ones. Deflate the tire, put the stem of the tire into the hole in the rim. Make sure you have the tire oriented the way you want it. Once the tire is on the rim, sit in the chair, hold the rim with the stem up. Grasp the tire about one spoke hole away from the stem and lift it up. Squeeze a bit of glue onto the exposed sections of the rim. Move the glue tube around to get a light coating on the entire surface. Release the tire, being certain that the base tape is centered, rotate the rim two spoke holes, and repeat the process. Do this until you make it back to the stem.
If you get any glue on the tire, rim, spokes or yourself, wipe it off immediately. Use mineral spirits as necessary to clean the glue from any metal that it gets on.
Once you've completed the gluing, inflate to about 25 psi. If any glue oozes onto the tire or rim, wipe it off immediately. Also make any manipulations you may want to center the tire if it hasn't gone on quite as straight as you want. You may need to decrease the pressure in the tire to do this. After 30 minutes, inflate the tire to about 40 psi and let the rim sit over night. I've had no problems riding on the tires the next day.

> loop the tire into a figure-8
> stand where you can be safe on one foot (where you can lean on something solid), and put one of the loops under a crooked or bent knee with your other leg mainly straight
> put one arm and shoulder through the upper loop on the same side of your body
> make yourself solid on one leg by leaning on the wall or whatever, and straighten slowly to gently stretch the tire
> when you feel it's enough do a trial slip-on; if it goes as smoothly as you need, start the gluing.
He also recommend after the glued tire is straightened on the rim, to inflate full pressure (CONI calls this "blocked") for half a day before riding. In my experience it works out ok if you just inflate it fully and then ride it. You want the blocking to settle the tire into its bed of glue. In my experience that is adequate for road riding. It might not be good enough for actual road racing - crits and longer rides.
Another way to stretch with more force (not necessarily recommended), is to drape the tire across your back and riding on the points of your shoulders, and catch the other side of the tire under two feet. You can press up gently as does an Olympic power lifter, but listening and feeling for the elasticity of the tire. I always find this loosens the tire, but I'm worried about excessive strain on the tire. That's why I say its not necessarily recommended. At the same time I haven't had any carcass failures on tires I've stretched, as far as I know. It brings the strength of two legs into the action, but most of us on this site probably have stronger legs than most modern Internet readers!
FWIW, I've always been reluctant to use Fast-tack, because of the apparent risk of losing the base tapes. If it is stuck so tightly, I'll probably destroy the rim strip pulling it away from the rim, the tire seems useless without a base tape, and I don't know what accessible glue is stronger than rim cement and compatible with the chemicals in the carcass of the tire. I don't accept that the reduction in mounting time that results is worth the loss of an otherwise good and pricey tubular tire, or to send the whole tire to Tire Alert to have a new base tape installed. If one lives with a stock of ready tubulars, ok, but while I have a lot of them I still don't want to sacrifice the use of my tire. Tubulars are not such a novelty to me that I would happily go out and drop >$200 on a pair of FMBs just because I now have a mismatched bike. I started using tubulars in 1969.

Hi. Me again. I pumped my tires up to about 160 p.s.i. a week-or-so ago, and haven't ridden the bike yet. Now, both my tires are flat. Does air leak out of tubular tires more quickly? Or is it just from the fact that the p.s.i. is so high? The bike has not been in the cold.

Doesn't mean you "don't" have a leak though.

A day or two for me - but I'm putting 135-145psi in them. Vittoria Corsa Control G+ w/ latex tubes.
Good upper body exercise, though, so win/win

Turns out i might have to join the tubeless team after all - Got my hands on a Puch (AD) Royal force which came with tubular tires. Will have to put that glue to good use now

Hi. Me again. I pumped my tires up to about 160 p.s.i. a week-or-so ago, and haven't ridden the bike yet. Now, both my tires are flat. Does air leak out of tubular tires more quickly? Or is it just from the fact that the p.s.i. is so high? The bike has not been in the cold.
