I figured the BB was toast but I certainly didn't get a lot of life out of it. Good to know about the FSA platinum as I am looking for a replacement. I have one other crank (low mileage) with a Shimano octolink BB. I think when it goes, I'm dumping the crank and getting something with a more durable BB.
