It was in good shape except for needed lube.

Although it's four years old, it's on a bike I use for
MTB/trucking/boating in summer and "bad weather" during
winter, so it isn't used frequently like a general
commuter. Other bikes get more miles on them.

Corrosion is a definite possibility. Need to lube it
more frequently.

Think I saw the KMC in Nashbar/Performance but wasn't
sure as to compatibility issue with SRAM and with 7 speed
chains. I think 6/7/8 are all compatible but am not
certain.
