If the tires hold sir they might be okay. However you can't trust a glue job for more than two years. I would just re-glue them and then test them on a few training rides.

Used to be an old story Lance would only ride tubulars that were aged for 5-7 years;)

Unless you can find obvious spots where the glue has let go, they will be fine.

Did conti use latex tubes in that era ?

Only because I dragged out my retro MTB (air B latex tubes) and both tubes ruptured when I pumped them up. When I stripped them down the latex had degraded somewhat.

It was years ago now but from memory, tubes probably had a couple of years use. Bike was probably stored for about 12 to 15 years (in a shed / no UV).

I don't know if this was common / expected or if some other random factor was at play.

WD :-)

AFAIK Conti have never used latex in their consumer tyres. I installed a set of Conti tubies on my race wheels in around 1991 and only replaced them in 2003 because I switched to Vittoria tyres with latex tubes. The tyres were still fine.

If you're happy with the tyres, I would remove and re-glue them. If you're worried about them holding up, I would pump them up to 140psi and see if they hold. If they do I would keep using them.

I was in this exact same situation 6 months ago. Same tires even, prob 12yrs old. Had them on both race wheels and training wheels. I pulled off all the tires and simply reglued back on 3 of 4. Good thing I did too, the tires came off the rims pretty easily. The only tire I actually replaced was the rear training tire because it was pretty worn.

Then, as I got to doing more reading, I realized how much better modern tires apparently are then my old Sprinters. So I bought new tires and swapped them in for the old Sprinters on the race wheels. So I've 2x perfectly serviceable 12yr old Sprinters hanging from a nail in the garage, ready for service should duty call.

Once saw a video about the service crew for one of the major long time TdF teams. They showed the basement "aging room" where hundreds of tubulars were draped on racks to mellow out for several years. It looked like a ham or wine storing area.

Wine, aging tubulars, blood bags...everything a contending TdF team needs. Did I miss anything else? Oh and I will be glues to the feed from France for the full 3 weeks!!!

How many tubulars have you rolled?
Fine me one person (aside from you), who would say you shouldn't re-glue a tubular every other year? In this particular case we are talking about a 10 year old glue job.
