I was pondering the ultegra vs. Dura ace thing. Given the construction is nearly identical, I think the difference in reported failures is probably just a selection effect? Number of units that get fitted to bikes and the cumulative hours of use?
Iβve probably seen about 10 6800 chainset failures now including one of my colleagues. Seems to only be an issue with 6800, not seen it affect any other chainset. I think the design has been corrected on 8000.
