Finally the crank that I always want

Finally I found the crank that I always want under my bike list. Shimano Dura Ace 7800c.

It is the one and only also only batch of crank that shimano had made in carbon series. It becomes limited edition as it has only 1 batch released in market. And become rare item although it is carbon but it does not weight light like those carbon crank. Stiff and strong which allow more effective power transfer I would say.
