4 years!

Breaking a chain is indeed a rare event--- but so is riding with the
same chain for 4 years; unless you don't ride that bike much at all.
Chains on geared bikes rarely last more than 2000 miles or so, and even
that requires regular cleaning. Replace a chain when the measurement of
12 full links exceeds 12 + 1/16 inches. Waiting until 12 + 1/8 inch
will often mean having to replace the cassette as well, which may very
well be your fate. You'll be lucky to not have to replace the chainrings.
Don't bother to replace just the master link. This chain is worn out,
unless you only ride 500 miles/year.
