Precision Ball Bearing Inside Frame!

I was cleaning out my bottom bracket and one of the ball bearings got out the cage.

The thing about my frame is that it has holes that allow ball bearings to go through and this time, the ball went through the hole and is now stuck inside my frame.

Its pretty annoying as it makes noise everytime I ride it because its moving all around.

Any suggestions on getting it out??

Where did it go?

If there's no cables or bearings in that part of the frame, a drop of glue could capture the ball bearing and keep it from rattling.

I think Gorilla Glue would work. It foams up, so test with a small drop on a bottle cap or something similar, to see how much it expands. It takes a couple of minutes to foam. You won't need much. One drop into the hole, wait a minute or two, then shake the frame until the ball sticks to the glue. Wait an hour for it to harden. Gorilla Glue is useful for a lot of tricky gluing projects.

Fish it out with a magnet...unless it is a ceramic bearing.

this was a common prank we pulled when I worked at a shop. pull the seatpost, drop 1-5 BBs down there on the other mechanic's bike. preferably push 'em into the top tube. wait for results.

Are there such a thing as non-precision ball bearings?

Maybe BSO bikes come with those.

Sure. They come in a variety of sizes, whether you want them to or not.

I would think that the fastest way to do this would be to remove yoru seaptost or to remove your bars and just pull your forks out. Then shake and use gravity.
A lot of frames have holes in the top/bottom tube near the center of where they welded them onto the headtube (YMMV).
I've been told that this is done so that ventilation can exist when welding to prevent any warpage.
No clue how true that is.

Ahah. I did that once.
Someone at the bike place taught me a trick to prevent that from happening when threading spokes. Keep a broken spoke around, and thread said spoke onto the TOP of the nipple you're about to insert.
Then, you can just hold it there while you thread.
Same goes for un-threading it. You thread onto your broken spoke as you un-thread the nipple.
