Which parts of a bike have reversed (left-handed) threads?

There's 1) the non-drive-side left pedal-to-crank threading and 2) the drive-side right bottom bracket cup (apparently sometimes called the fixed cup).

Is there anything else?

  • What country is the bike from? French/Italians are contrary to the usual rules. – Batman Sep 10 '16 at 18:44
  • @Batman Mine was made in China for the American market but I'm also asking for general knowledge including how it's done in other places. – compton Sep 10 '16 at 18:55

    My point is that you have to be careful. There are bikes which use the exact opposite of the sane typical choices. – Batman Sep 10 '16 at 21:56

    The left pedal, always! The BB depending on the standard. – Carel Sep 11 '16 at 10:52

Fixed gear hubs have left-handed threaded lock rings, so that they can't be loosened when the cog that is on right handed thread is turned counterclockwise.

I've just found that a freewheel internal thread is left-handed. This is the access for the guts of the freewheel's insides, so pawls and little bearings inside, and generally not user serviceable.

On some full suspension mountain bikes some of the pivot/linkage bolts can be reverse threaded. Manufacturer dependant though.
