Thanks jim ... great to see old friends and meet new ones. Other life-stuff had my attention for a time, but it didn't keep me out of the bike shed — and gluing cheaper tubs :)))

Good read

(easier that the tufo s33's which were my first foray into tubular), I did remember to be patient, put the tire on slowly pulling it out so to speak.
next up will be doing the glue, I have used tufo rim tape before. the fun thing is that after I fix some broken spokes i will be able to do a direct compare between the Challenge Elite Pro 25mm, the tufo s33, and even some michelin pro4 clincher on the same bike So, to answer: a 20 second moderately forceful stretching with my body, then four days at pressure on the installed rim. I rarely do the body stretching, because once I heard the faintest sound of a tear while performing it. I didn't hear any thing from the tires, this time. I only chose to do a body stretch because I could not make it budge onto the rim with the usual "stretch it on" technique. To add: I see what I did as stretching rather than aging. As far as I know I've never aged tires in any "formal" way. That means to me, I not only know when I put them up, but I know how to tell when to take them off. I have old tires that are unused (these Gommi's), but if aging requires having them on rim so that they become shaped to the form of a tire rather than a folded ribbon, I have not done that. I have also installed freshly bought tires. I can't say I see any difference in the behaviors of the tires. I am also doubly a sinner because I have a furnace with a large fan motor within 10 feet of the Bike Room ... mea culpa! But I have not observed a problem. |

I usually just let them stretch for a day or two. If you can get them on and off the rim without too much trouble then doing the same once you have applied glue isn't so much harder.
As for glue, I finally ordered a small can of Vittoria mastic and bought a bunch of small inexpensive artist's brushes from the local hardwrae store. Applying glue to either tire or rim with a brush is so much easier than squeezing it out of a tube. I've re-used the brushes once or twice but will most often just toss it and use another. Prepping tires was never so easy. |

as I am getting closer to actually gluing tires and finishing my build, the question came to me: do people pre glue the spare when the spare is a new not mounted tubie (I have stretched it ) or not. If not, then is it just put it on and ride easy until a proper gluing can be done? (I have seen comments that many people use and old tire that is just old or old an repaired as a spare and as such has glue

More often than not, the spare was a repaired tire that already had glue on it. That is correct. Back in the days of Clement red, if you procrastinated for a while, often braking heat and residual glue would melt the old glue and stick the spare on pretty well, especially during summer. |

The thing with installing a spare on the road though - pump it up as high as you can get... the pressure is what really holds it on... and take it easy around corners, and watch the downhill braking forces. https://lh3.googleusercontent.com/Gr...=w1024-h744-no |

Two recent ones. Had a flat on a very fancy top end tire. Don't care to reveal the brand. When I started taking the tire off the rim it was OMG. The tire carcass was completely unattached to base tape. Base tape was quite solidly glued to rim but wasn't attached to tire any longer. I must have been riding a long time in that condition. Air pressure held it on. The valve stem was not even crooked. The mechanic who told me this one asked me not to name names or publish on my blog (which there isn't). Bought a previously glued but not ridden silk CX tubular from the quiver of perhaps the senior luminary of American CX competition. Looked at base tape and it was a very basic glue job. The guy at the swap selling the tires was the mech who did the glue. He has a lot of tires to glue and he keeps it basic. One, two, three, done. He asked how long I'd been gluing tires. Since 1967. OK, he says, you might understand. I tell people how I glue and they never believe it, think I must be keeping secrets. Glue rim, glue tire, wait ten minutes, tire on rim, pump it up. An old one. A friend used to get a big box of tires every November from Team 7-11, from Jim Ochowicz. Tires to be patched. This was back in days of red glue and the glue on base tape was plain as could be. Two seasons running the tires arrived with a short run of glue from spoke hole to spoke hole and then three spaces spoke hole to spoke hole left blank. A 32 spoke wheel would only have eight short strips of glue. A 28 spoke wheel would have seven short strips of glue. These were tires with marker pen names PHINNEY, BOBKE, HAMPSTEN, CARMICHAEL, DAG-OTTO, ALCALA and so forth. Glue your tires and expect it to work. Avoid 60mph descents on unglued spares. Don't worry. |
Also, my first few times I used too little glue, and i could easily peel the tires off when deflated after a ride or so - they stay on ok when inflated. But I didnt push the tires too hard initially. |

Now, since they're taped, the tape generally stays on the rim, so the spare sticks just fine, and the residue tape gets me home. (But then I can't use a cool word like resiglue.) |

I've never preglued a spare but some guys I worked with used to do it. I don't worry about prestretching them either since the tighter it fits the better.

I usually preglue a spare, when I'm gluing the tubs I'm riding on. Takes just a fee minutes to do, and after a day or so you can fold it up and it's ready to go. Hopefully not needed, but nice to know that it's there.
I've heard that once installed, braking warms and softens the glue on the spare and gives you better adhesion. Can't speak from personal experience on that as I prefer to take it easy on a freshly-mounted spare. No real reason to test the limits of adhesion and risk a much larger problem than a flatted tub. |
while I am keeping the thread busy, does anyone have any experience with wheels from Bicycle wheel ware house?

Still in business. Checked site, seems to be same place. Good wheels back then. Pay extra and get light spokes, you'll get more out of the Reflex rims. Which just have to be old stock, a good thing in this case. The DT 2.0/1.8 are so minimally butted always made me wonder why they bothered. 2.0/1.5 rides better. |

I think these will be interesting , not sure if their seta's . Right now there are stretching , although I have never done the two aged coats and one fresh before mounting I think I'll do it this time . I can change .

I'm riding my track racing bike after not using it for a few years. I've lost my nerve. I'm afraid my 22mm tires (Continental Sprinter) will slip, even though I know they won't. I'm just nervous, especially when I see a groove in the road. Does anyone have suggestion for rebuilding the confidence? I weigh 170 lbs, and I'm pumping them to 100 psi.

Well, it's a tubular Pave'. I have 5 unused ones left in my stash. I do have open Pave's on my clincher wheels though (ordered "open" by mistake) - almost as nice of a ride.
Very well executed :thumb: - I suggest closing your valve though, so the stem doesn't break off. |
My dear Tom , it's all in your head . Re glue ,and forget about it . Whoever said N+1 does not include a track bike ... Well I don't know , not my opine .

Had my first tubular flat, ever. Tufo Hi-Composite Carbon 25, so yeah, I'm ticked. Tire looks great, like new condition. Culprit is the valve stem (not the core). Stem "joint" is bad. Tilt it one way, fine, another, air escapes. At 100 psi, it was leaking slow, which I thought was the core. I replaced the core, pumped it to 100, ran a construction gauntlet (mostly sidewalk to avoid steel plates and debris), and 1 mile later, the road roughed up, but I looked down just to be sure: yep, was running a carbon rim on a mostly-flat tire. Slow ride back, replace tire (tape, dude!), eat lunch, stew a bit, and then back on the road for 36. .....I think a flat on a tubular, on a modern bike, is more disappointing. Not sure why. Zipp 303 on a Wraith.... aargh. |
