Way cool build and lots of exotic jewelry adorned on your bike, love it. So looking at the numbers from a Weight Weenie point of view which seems your path, these are below weights of what you have and not exotic. I have a few more to show you that were massed produced and stand up to or beat the Ti numbers. Specialized Ti spindle pedals made in Japan with composite body and steel screws (alloy or Ti would lose some weight), Ritchey Z Max tires, likely Japanese made, for race only (that's why we all bought them). You opened this up for debate since you wanted the lightest parts, just sayin...I hope this does not upset anyone, was trying to show and have a few more examples, that money does not produce light parts, innovation did. Titanium is not lighter than aluminum, just more durable.
