on the vanity of man & the law of diminishing returns 
Almost guaranteed to wear out faster, will not perform better, so it's purely a weight weenie thing. Will probably theoretically save 1 second over a 10km climb.
It's just funny to me. I do run a carbon crankset, but it cost me 100 something bucks!
Prada needs to start selling bike shoes, and Hermes should sell bar tape. The sad thing is, they would sell like hot cakes.
Yeah, that's too pricey for me. THM territory, but also THM weight. It is 220g or something for the arms, but my old sram carbon cranks were in the same $ ballpark as Serge, just 150g heavier.
IDK that they'll wear rapidly, there's a metal sleeve on the carbon where it contacts the bearings.
