Quoted message said:The problem is my front derailer makes
a slight clattering noise in the biggest

handlebar shifters and if I turn it -past-
the "3" and hold it there the clattering
stops.

still having trouble.

but I'm unsure of which way to turn
them. Is there a clear/clearer procedure
for doing this so I don't mess up the bike,
or should I take it into the LBS and watch
them adjust it?
Quoted message said:Seems like it should be easy, but I'm
worried I'll mess it up more, especially
since Sheldon's site talks about multiple
adjustments and adjusting the cable
length also.

Sounds like you have GripShifts, or some clone. I don't, but all
shifters work the same way. They pull the cable a certain amount and the
derailer moves a certain amount. ALL adjusting screws are right hand
screws. i.e. "Righty tighty, Lefty loosey".
If the chattering stops when you turn the shifter past 3 (by this I
surmise you are now referring to the front shifter), then your cable is
too loose. There should be an adjusting barrel somewhere along the
length of the cable, most likely where it leaves the shifter. Unscrewing
this barrel will tighten the cable.
Put the bike in the big ring and unscrew the barrel until the chattering
stops (you should be in the smallest cog when you do this).
As for the smallest rear cog, when you shift into it (or try to), is the
cable leading to the rear derailer slack? If so, the high gear limit
screw on the derailler is too tight (they should be marked H and L, you
may need a magnifying glass and bright light to see them). loosen the
one marked H.
However, if the cable is still taut when you try to shift into the
smallest gear, then your cable is too tight. Look at the rear of the
derailer where the cable enters it. There, too, will be an adjusting
barrel. If possible, screw it in (righty tighty) until the chain will
shift into the small cog.
BTW, assuming they're valid, the only DUMB questions are the ones you
don't ask. Have fun! :-3)
