I had to get an o-ring for one of my hubs. The previous owner had used RTV and I don't want to mess with that if I ever need to do a trail repair. Anyways, I had to get a pack of 10. These are the large diameter o-rings that go on the hub lockout outer ring and seals to the hub itself. I also have the o-rings that go around the dial. I'd like to get $3 per set. That would be (1) large outer o-ring & (1) small dial o-ring for a total of (2) o-rings. I'll just throw them in an envelope, so no shipping.
