The US postal system seems pretty good to me. I mailed some bike parts back to Chris King in Portland, from Philadelphia.
I mailed the package at about 5pm on Tuesday night. The package was delivered about 1pm the next day. Cost: $5.45, including delivery confirmation.
Nice. Very nice.
Chris King had already sent me replacement parts. This was the return of the broken part.

That part threads into the hub and is the part of the hub assembly which contacts the bike frame. I have no idea how that part sliced off. The tech asked me if I’d tightened it too much. I hadn’t touched that part since the hub was upgraded to take a disc brake rotor.
