I'll consider it Jim. Mine is the elusive last generation light weight aluminum pulley. I'd hate to sell you a rock and hate to give away a diamond. Most indications are it's a rock. It has a new NSK bearing in it.
It never slipped.
It rattles so badly that I thought it was about to explode.
For someone that knows, it should be easy to repair. I don't know that someone.
Or do I?
