Adjustable Dropouts

Larry said:

I have adjustable dropouts an a Look Carbon Frame, would you think it better
to line the rear wheel up with the seat tube which makes for a slightly
nosier drive. Or would you go for the wheel being slightly further away on
the cassette side which makes a silent drive ? This puts the wheel amount
4-5 mm off center on the seat tube.

Line up the wheel with the center of the frame -- which one would presume
is the center of the seattube. If the drivetrain is noisier that way,
then something is out of alignment there.

The back wheel must follow the front wheel. If the drive is noisy in
this position then your derailleur needs adjusting or the hanger is bent.

The adjusters are there to compensate for poor framebuilding, or to
allow an incorrectly dished wheel to be used if you are given one in a
race, for example.

Yikes....Center the wheel in the rear of the frame, right behind the seat tube.
If it is canted, then the cogset is too and will not work correctly. These
adjustable dropouts are to move the entire wheel forward or aft, not to tilt it
one way or another.

I follow what you are saying, but you have no choice in adjusting the tilt
because there are two allen bolts that hold the aluminum part's that slide
back and forth about 1 cm. What I am saying is if the center of the wheel is
4-5 mm to the cassette side of the seat tube the drive train is silent. If
you center the wheel on the seat tube there is a tick in 6th gear that can't
be adjusted out. I have no choice but to adjust tilt because both sides
slide. Am I better off with a centered wheel or silent drive train. I don't
see a way to get both.

Then something is wrong with the frameset, the dropouts or the der hanger.

Or the dish on the wheel (seems likely).
