    When is an old sewup too old?

    I have a bunch of Conti Sprinters and Vittoria sewups all on wheels or stretch rims from racing days. Some of these still look like they could be used (don't see any dry rot and they hold pressure well). They have been hanging in a humidity controlled basement. Only issue they may have is base tapes pulling away in spots.

    When are sewups too old to be mounted for one last comfy ride?

    As long as they're not falling apart go for it. Just make sure to pull them off and re-glue if it looks like it's dried out. My rule of thumb is 1 year at most, then glue them again.

    Buy yourself a bottle of liquid latex-this will get the base tape to adhere, and for old gumwall tubulars, brushing it on the sidewalls will give them more life.

    I had a jar, but it goes bad so quickly. Used it for both of those purposes you cited.

    Might be nice to run a Campy hub with a GL330 again.

    You don't say how old they are, but keeping them in a cool, dry place they will last for many years. Over time the tread rubber will slowly oxidize and harden, which will result in less traction and faster wear, but you can't really predict how fast this will happen. Ride them. Or better yet, sell them to some tubular fanatic for a high price (vintage tires!) and convert to quality clinchers.

    I scored a box of 6 old Clement Super Condors a few years back that were unused, stored properly, and got the entire batch for a measly $30. As a simple, light cotton casing tubular, they were certainly not meant for the roads near me, but they folded up so small and were so light, I've used them as spares for the last 10 years. On one bike, I go old-school and strap one directly to the seat tube. These tires must be 30+ years old, but not a sign of dry-rot on any of them.
