I also use their glue or mastic remover, when cleaning old, glue laden rims, back to their original condition.

Extremely valuable information for me., Thanks. Primarily because I do not carry a cell-phone and I might be walking back home 30 miles in vintage cycling shoes, although the people around here are really nice and will usually collect any cyclist in trouble. I can't take any chances: I'm bringing an extra and leaving this bottle at home.

"Pre-glued"?! I was hoping I could just put the spare on there and use the glue that was already on the rim. Maybe not. Maybe put glue on the tire when and where you puncture?
For tape...IME some of the tape may stick to the tire, some to the rim, or all on the tire. Never had one that all the tape stuck to the rim. I carry a small piece of stiff sheet plastic with tape wrapped on it to use on the road. Also have a small sharp knife to cut tape as needed. |

Yes you do. The latex compound with the particles clogs up any would-be-punctures and only minimal air should escape.
Regarding the valve core, that is up to you really. If you remove the valve core, all the air will be let out anyways. So you can either deflate it beforehand, or just remove the valve core right away. I think the amount of sealant is also dependent on the size of the tire. Stan's might have a reccomendation, but imma say go with 40 mL (since i presume you run a 25 mm tire at most) |

An unglued tire might hold okay. Putting glue on at the time is an iffy proposition. Easier to pre-glue a tire and then you have a better chance on holding and spend less time at the side of the road.

Thanks for mentioning this. Is this something I can use to get the glue off of the side-wall of the tire as well as the rim?

The rim, definitely. The side-wall, my guess would be, yes. However, I've never had to use it this way. It is very VOC friendly, and barely has a smell that I notice. Also, Mrs. PB never complains when I use it in the garage. It would be worth the try.

Back to this post from a week ago--unfortunately Velosaloon informed me that they can't ship Conti cement to the US because USPS bans flammable items in the mail. They refunded that portion of my payment. Fair enough.
What's not cool is that I put in the order on Tuesday 2/28 but didn't hear back, except for the automated confirmation email, until I enquired by email a week later about the status of my shipment. So today I get a response that the package, minus the can of glue, supposedly went out on Friday 3/3, but the refund didn't happen until today. This is seriously backwards. I can live with their system not flagging the cement as not shippable to the US from the start, but then I need to be informed, and my money refunded, as soon as they do notice. I've made it clear that I'm not a happy customer. In German :notamused: |

My rule of thumb is that if I didn't have an immediate pressure loss (think large hole), I will apply sealant, inflate and go. I've learned the hard way (repeatedly) that adding sealant when there is a big hole is a recipe for mess, so I just put on my spare. |
So, back to square one in my quest for glue. To recap, I snagged a pair of Sprinter Gatorskins when they were briefly priced at $17 ea. or whatever it was, and they're going on the bike I'm building to try track riding/racing up in Londonderry, NH. It's a bumpy old outdoor track with wide, modestly banked turns, and I'm a spaghetti-legged almost 56 year old who's never done any racing before. Still, I would prefer glue over tape just for the peace of mind on a hot summer race day.
I guess for just these two tires, 2x25g Continental in tubes would do? Those are still easily found here in the US, looks like around $16 shipped give or take. Or does anybody have experience with Specialized? $28.99 for 120g, shipped. ETA link: https://www.specialized.com/us/en/tu...Text=0332-0100 https://assets.specialized.com/i/spe...h=900&fmt=auto Derived from the most used and proven European recipe that has carried rubber on wheels for the Pro Peloton for decades. I searched the thread but only found Specialized tires, not glue. Looks like last year around this time they were selling off track tires at $29 each, dang. |
Might as well add that Specialized only has three tubular tires left in their line-up, two of which are on sale for $75 instead of $100. Looks to me like they're getting out of the segment.

Bringing a roll of tubular glue-tape along on every ride seems ridiculous. https://cimg8.ibsrv.net/gimg/bikefor...92d12f38d5.jpg Other bike riders see this and are either completely baffled, or immediately recognize sew-up tifoso. The Hell of the North is a great tire |

I don't like to fold the tire with the tape against tape on pre-glued tires because it puts too much stress on the base tape when I separate it.

And sadly, there's no way to get a clincher of any sort on to get you home. (Unlike the reverse. If we carry a spare, anyone with a 700c wheel can roll home on it.) Now, 50 years ago it might have been a long wait for another rider but he probably had a spare. |

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!) |

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 [MENTION=68015]DiabloScott[/MENTION] method, and a fresh roll of effetto Mariposa Carogna Tubular Tape. https://cimg5.ibsrv.net/gimg/bikefor...7ca8d1a2bc.jpg https://cimg4.ibsrv.net/gimg/bikefor...94250bff3c.jpg 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. |
