The argument was mostly over why Surly would release a complete bike with this issue, but lots of people run these cranks without any issues on all kinds of bikes.
My bike came with RD2s, which are the model with a 45 mm chainline according to other discussions. I do occasionally notice noise when the chain is dirty but one symptom I have is that the chain will shake/vibrate at about two point every rotation of the cranks at slow to moderate speed. I notice this when I have the bike upside down. For instance if I spin the rear wheel to verify it is aligned after changing a tube. It always bugged me but I just want to verify it is not a safety concern. I ride a front brake but still feel that a broken or thrown chain could result in some cranial damage.
