A NR doctoring thing: Many cages on these were crooked right out of the box.
They do respond to straightening; here's how: Check derailleur ear of rear
dropout with straightening tool, straighten as necessary.
Mount derailleur on dropout, remove pulley bolts, pulleys, back plate of
cage. After wiping cage clean, put a straightedge on the outer (still
attached) plate of the rear derailleur. If it doesn't run parallel to the
chainrings, bend it carefully until it does. You can use a crescent wrench
for this, I'm a VAR bending bar snob for this job.
Reassemble cage and pulleys, you should find the derailleur will run more
quietly and shift with less hesitation than before if the cage was really
bent.
