No, I am not. But thanks for volunteering your opinions. Shimano 10 speed drivetrains (all of them) are temperamental. They run great when finely tuned (which mine are) but they do need careful attention. Compared to the 9 speed Tiagra on the touring bike that just keeps going, and going. The only thing I do is to swap the chain on that bike every 4000 miles or so.
