Another approach: Break the chain and put it around the big-big combination outside the rear DR. You
should have about 1 link of overlap (1/2 to 1-1/2) between the chain ends when you pull 'em tight.
Put the chain back on right. At 1/2 link or so of overlap, make sure that you can shift into the
big-big combination without damage to the rear DR (shifting from the front or the rear) -- not a
normal combination, but most of us hit it by accident on occasion -- for me, it's usually while
night riding.
If you have a full suspension mountain bike, you need to do the above test with the rear suspension
at the point where it needs the most chain (fully extended for most, so not a problem).
Note that by a link, I mean 2 chain pieces
