Front Deraillleur Barrel Adjustment I'm working on adjusting my front derailleur; Shimano 105 group set 5700 series.  On reading on the net and also watching a couple of online youtube videos there is comments about the barrel adjustment used to either tighten or loosen the cable to ensure that indexing occurs.

Now what I'm confused with is that the notes often refer to increasing the wire tension via a counter-clockwise turn.  The question is counter clockwise relative to facing which way ?  For an inline barrel adjuster depending if i'm looking down from the shifter on the handle bars, or looking up from the cable end of the derailleur the direction is different.

Is there an easy way to know which way to turn ?
As the mnemonic goes: "Lefty loosey - righty tighty"

The indicated way to turn is always relative to the object the screw / the thread is fixed to. Examples:



If you turn the barrel on th rear derailleur towards the wheel, it's loosening. It tightens away from the bike.



The same goes for your STI: in this case loosening is towards the bar, tighening towards the front of your bike. If this was the STI on the right, it would be the other way round.
