Methinks they all got canned at that meeting, and nobody is left to change the message.
Good new is, as of this writing you can still get replacement cranks from an authorized dealer. I took one of the recalled cranks (an FC-MC12 off a '95 Trek 730) to my LBS last week, and today received not only a replacement crank, but also a chain, bottom-bracket and derailleur. All entry-level stuff, but more than good enough for a 15-year-old hybrid.
I hate to bump this once more, but the recorded message on Shimano's phone line is still the same more than 1 year later. I have just encountered a problematic crankset that may fall within the lines of the recall.
What was failing on these cranks specifically?
