[QUOTE=Lascauxcaveman;18492466]I've got a 3x7 RSX brifters question (at least it was sold to me as a 3x7): the left 3x shifter seems to be working consistently, "click click," but it doesn't move the FD very far on each click. I have to click all the way (two clicks) just to move up or down one chainring. Is this likely


It looks like the software is cutting off your quote AND not closing your quote as it should, but here is my reply:

Firstly sounds like the cable is far too loose, such that the first click may only be taking up cable slack(?).

Secondly, if you roll the rubber hood forward, the lever part number is visible, usually the triple shifter part number ends with a "3".

Like RobbieTunes mentioned, "zeroing out" the lever (stabbing the small lever until all cable is released) and then tensioning the cable to just remove all slack should correct any cable looseness, but again as RobbieTunes mentioned, the limit screws need to be in the ballpark first, and that part requires some degree of familiarity with front derailer setup.

Hi limit screw on the oddball, "top swing" RSX front derailer is toward the LEFT side of the bike(!). Should allow a smidgeon of clearance between the chain and outer cage plate whe the chain is on the big chainring and smallest cog.

Lo limit screw of the RSX front derailer is on the RIGHT side of the bike, and should allow a smidgeon of clearance between the chain and inner cage plate when the chain is on the small chainring and largest cog.

Lo and Hi limits are how far that the derailer can move through it's motion range as adjusted. This regardless of what the shifter and cable are adjusted to do, but you can experiment with cable tension and move the levers to reach both limits so as to move the derailer and establish the limit screw adjustments.
