I wasn't that surprised that the guy didn't know how to tighten the crank. I was rather suprised that the Sag people, and the others at the rest stop didn't konw how to fix it. One minute with a multi tool and he was riding again.
That was nice of you to get him back on the road again but he'll likely be in for many retightenings of that same crank now that the precision fit of the arm and axle has been destroyed by riding with it loose. Was it an FSA crank?
