Quoted message said:Pat in TX said:This might seem like a dumb question for you, but it has been bothering me
for awhile. When someone says to turn the cable adjuster one half turn
counter clockwise, how is the person oriented? If I am on my bike and reach
down with my right hand and turn the adjuster counter clockwise, that's
clockwise to someone standing in front of the bike. So, can you tell me
which is it? Are those directions understood to be used by someone standing
facing the front of the bike? Thanks,

Usually counter-clockwise and clockwise directions assume the (home)
mechanic is facing the head of the screw or bolt. Where you are seated
is irrelevant. In the case of the cable adjuster, the part that rotates
is the bolt, so looking down at the top of the adjuster is where you
would be turning it counter-clockwise per the instructions.
This works because almost all screws and bolts go in clockwise. There
are understandable exceptions like bottom brackets.
Easier to remember than "screw in clockwise, unscrew counterclockwise"
-for those of us who are dyslexic - is the age old mantra: "righty
tighty, lefty loosey."
One other point: there are usually two barrel adjusters for the rear
derailleur, one attached to the derailleur and one attached to the
left side of the frame. The one attached to the frame enables you to
adjust cable tension while you are riding. Since when you are riding,
you are therefore not facing the head of the frame barrel adjuster,
but rather are "behind" it, you will have to remember to turn the
adjuster in the opposite direction: "righty loosey, lefty tighty."
Same as when adjusting spoke nipples on a truing stand.
