yeah, I know it's not just the CR1, it seems to be a growing trend with composite road frames.

But I can't really see the advantage of not having a replaceable hanger. Obviously in a crash situation it is much more likely that this type of frame will be destroyed than, say, a steel frame. But is my CR1 any less strong in a crash than, say, a CAAD7...? I don't think so, but let's not open up that can of worms. But a derailleur hanger can be bent or damaged in other ways, would be nice to have the option to fix it myself, and I can't see wh there is a growing trend away from this.
