11.4, have you read the thread?
5 8 5, yes, I actually did. And I read the Australian thread. And I called CPSC. And I talked to Shimano. Now what do we have? One rider who has broken three cassettes with virtually no mileage. A new poster here, and a new poster on the Australian forum (posting on the same subject). That Australian thread has someone who breaks cassettes repeatedly as well. OK. To break cassettes repeatedly, unless it's happening to plenty of riders, is called user error. It isn't a product defect until a number of riders have had the problem. Not two who do it over and over. Any quality control expert will tell you that only an attorney would try to make a case out of two users who break multiple components like this, and the attorney wouldn't win in court. Let's see photos from anyone else on this forum who's had a failed 9000 cassette. When we have a dozen, with photos, it starts to be real. Neither CPSC nor Shimano have seen any unusual level of breakage, despite what was mentioned in the thread. Let's see a scanned response from Shimano acknowledging the issue. Let's see photos from other users. This breakage pattern is user error.
