For removing old glue from tubular rims, I've had excellent results with a small propane torch and a rag. 'Found this technique being demonstrated on a YouTube video some time ago. I'd recommend caution until you get the feel of it, but what you do is gently warm the rim until the old glue starts to bubble a bit. It will be really soft and that point and wipes off easily with an old cotton dishrag. I used two passes. About 90% of the old glue came off in the first round. The second time around left the rim with next to no glue remaining. 'Takes very little time.

Not all tubular glues are the same regarding removal. I find Vittoria Mastik is almost impervious to most solvents. (Acetone, MEK, Alcohol, Goo Gone.) . According to the MSDS, I probably need Xylene or Benzene. I did however have great luck with paint stripper (Methylene Chloride). It's nasty stuff, but it disolves it without much trouble.

Mineral spirits (aka paint thinner, petroleum naphtha, coleman fuel) is my go to solvent. Out here in California, we cant get the good paint thinner anymore, so I use coleman fuel, which is the real stuff. Camp Fuel for gasoline stoves from walmart for $7 a gal. If the glue is not totally crusted red stuff, I soak a rag, 1 ft long and lay it on the rim for a bit. Then I use a razor scraper. If it is newer, the glue comes off like butter, older needs some work. For that crusted red stuff still on from the 1970s, just the scraper and elbow grease. |
Has anyone tried Challenge Tubulars?

Yes. They are my favorite cyclocross tubulars (the Limus is a spectacular mud tire). I also run a set of Strada 300 TPI 25mm on the road. They are very easy to mount, and easy to get on straight.
I ordered a set of the Criterium's in 25's. The pricing on the Vitorias and the Veloflexes are getting a little beyond my price range. |

The tires that came with it were glued on but do not look to have been ridden, wheels look brand new after cleaning. The tires are probably 35 years old, very nice looking Vittoria Corsa CX tires. The side walls are shinny like they have been coated. I do plan on riding these wheels and tires. I see no cracks or damage to the tires and the base tape is still intact. Are these by chance silk? If they are silk that would really be cool because I have heard so much about silk tires? I did not ride tubular tires in my youth, these will be the oldest tires I have ever tried out. Will they be safe after all these years? |
Nice wheels, Steve! I do believe the tires are silk. As for the safety of the tires, I would keep a close eye on the glue connection between both the casing and the base tape as well as the rubber and the casing. I had a close call on those very same tires. It was a warm day and I had just finished watching the end of a Tour of California stage which finished at the top of Mount Diablo. Descending down the mountain, weaving through cars and spectators and other bystanders who had come out to the mountain to watch the race, I latched on to the wheel of a couple BMC riders who were also making their way back down the hill. I heard a little flap flap flap coming from my rear wheel. I thought it was maybe the base tape rubbing against a brake pad, but I was having too much fun to stop. When I finally did check at the bottom of the hill, I saw that a good 8-10 inches of the rubber had completely separated from the casing. :eek: personally, I would still take my chances with those excellent tires, but I would definitely check them regularly and not just at the base tape. Keep an eye out for a little curls at the edge of rubber. |
Corsa CX were cotton, not silk. They are very high quality racing tires, and more or less replaced the old Clement silks when they came out.
I don't see any visible signs of rot -- often it is quite obvious, but it'd still be careful with these. Cotton does decay, and these likely date from the 80s. |

Too many good newer tubulars are available now for me to want to ride 30+ year-old ones though. https://cimg4.ibsrv.net/gimg/bikefor...622d0f12df.jpg

Thanks for the info diabloscott , Salamandrine and gaucho777.
. I am a bit disappointed that they are not silk. I was buying the wheels assuming that the tires were just junk anyway. I was surprised that they even held air. I am torn now. Not sure I want to ride them always worrying but hate to just toss them in the trash. I have no dangerous hills to deal with around me so maybe I will try them out and watch them? Keep them on the trails and see if I can get a season out of them? Not sure there is a market for 35 year old tires except for maybe people with wall hangars? I think the wheels would look pretty cool on the Peugeot with period correct tires? |

I think the wheels would look pretty cool on the Peugeot with period correct tires? If you're not riding fast descents, it might be OK. They at least look good now. Rotting cotton tires are pretty obvious since they basically start to fall apart. Safest to only run them on the back. Keep in mind I am very conservative and careful with tires. I won't run a patched tire on the front. I like to know I can hit 60+ on descents without worry. |
Latex rubber usually get that dark, shiny look when they dry out. That is how most hoods look when they start to dry out and get hard. I would say that is usually not a good sign if you see it on the sidewalls of an old set of tubs......
The inner tube should be in better condition as it was not exposed to the elements, so it will still hold air. I will not trust the casings as much. You should try out Vittoria's new Graohene compound Corsa tires to replace them. They feel really fast and light! Not cheap, but worth every penny, IMO..... and the big plus is, they come in tan sidewalls too, for C&V bikes!:thumb: |

Will they be safe after all these years? Two Vittoria Special Pro Racing Team, 22 mm, cotton. I've had them inflated on rims for about 3 weeks. I'm convinced the tubes are butyl. One Vittoria Corsa CG Ultra P-R Squadra Prof, also 22 mm cotton. This has beet carrying pressure for about 1.5 weeks. Butyl tubes as far as I can tell. I just set up my Challenge Parigi-Roubaix tubulars, on rims, 27 mm (more like 29). It's only been a day, but this morning they went onto the rims well and they are still hard after 6 hours. Can't say what the innards are, yet. I have a few pairs of Gommitalia Espresso, handmade and supposedly latex. So far I've had trouble stretching them initially onto rims. Once I can get a pair of those to mount and take air, I'll have four decent pairs of sew ups in usable condition! |

That's a deal. Just wish they came in a Tan Wall.
i ended up with a pair of corsa speeds with the tan wall, the tan does look sweet, even on a modern bike |
I don't think they make them in the green anymore.
|
From what I’ve read, the pave is discontinued for the corsa g+control, so these are old stock in any event. |
