Cork in the seat tube?

1. Was this a common back in the day? My 68' PX 10 has what appears to be a cork rammed in the seat tube.
2. How the heck do you get it out?


After I discovered there was something stuck in the seat tube, I took a piece of wood dowel and poked at it. I broke off a piece of what looks like a cork
Now, i cannot get the darn thing out.

I was thinking of the business end of a wine corkscrew welded to a 1/4" steel rod.

A long aircraft bit is the most sensible. In a shop we might have figured out a way to use compressed air, because it's fun and dangerous.

Try a wheel spoke or a wire coat hanger.

Iím thinking some previous owner stuffed some cash or paperwork or theft-recovery identification under the cork.

Remove the bottom bracket and use air pressure to pop the cork out, just be sure to have the opening pointing in a safe direction to avoid injury and contain whatever pops out.

I tried pushing from the BB side up. I cannot find anything that will bend enough and is strong enough to push it out. I think its stuck on the sharp edges of the seat tube where it meets the BB. Man, I am at a dead end.

That bellhanger bit in post #7 will work. Just drill through a couple times to weaken the cork, run the bit down into the BB, loop a wire attached to a nut or washer through the hole in the tip of the bit designed for this purpose, and pull it out. All you need is a readily available bit of sufficient length.

Remove BB. Run a piece of all-thread through the cork, put a washer and nut on in the BB shell, clamp the other end in a bench vise, and yank on the frame.
If you donít have a bit long enough to drill the cork, you can grind the tip on the all-thread and chuck it in a drill.

If not in a hurry the cork moth (nemapogon cloacella) might work, don't let them spread to your wine bottles.

Using a cork in the seat tube was a common way of carrying spare spokes on long tours. Push the cork down "far enough" that you can stick a few spokes in it with the elbows up. If you need a spoke, just loop a piece of dental floss around the elbow and pull it out. Wrap a piece of dental floss around one of the seat rails and secure it with scotch tape. It actually is an ingenious solution to a common problem. Some frames, like the Surly, have a spare spoke holder on the DS chainstay, serving a dual purpose there.
