This has been driving me nuts.

A rotational noise coming from the back wheel. Tire is fine, Campy hub is smooth as silk, noise whether I pedal or call coast. I was all set to rip apart my hub and grease the bejesus out of everything. It's quiet in my garage today, it's definitely a rattle from the inside of the rim.

These are open pros with the reinforced eyelets, so the one and only opening to the inside of the rim is through the valve stem.

I already peeled the rim tape to see.

Shake and wiggle as I might, I can't seem to extricate my noisy friend.

I don't want to rebuild wheel done by someone with far greater skill than mine. I don't want to listen to this either.

I see three options, all are quite redneck.

1. Headphones
2. Spray the inside of the rim with 3m sticky spray and glue the pebble in place
3. Squirt great stuff, expanding foam into the rim to achieve the same thing as #2.

It's pretty hard to ignore.
