I just got ceramic bearings in my zipps and a new pulley. I am trying to get the most out of my fitness and hope this will allow for sub 2:10 in a half ironman. Now I have been using a new chain and 11 speed cog for race day but always went with a basic ultegra chain. I looked at titanium and dura ace and saw its just a small gram difference in weight. What does the ceramic chain offer? Does it have special bearings or something? If I am doing ceramic bearings in my wheels and pulleys should I do a chain as well or am I pretty well covered.
