Stronglight Pulsion carbon road crankset-481grams-amazing!!!

This is like a jewel in bicycle market. Very stiff and very, very, very light. It's considered as a lightest crankset available-with all screws, chainrings it weight 481grams!!! Bottom bracket is included and it's Sampson-184grams with carbon shell and titanium spindle, total it gives 666grams on my pesonal weight scale. If you get XXlight isis bottom bracket you can shave additional 70grams, so you can have crankset as light as 596grams!!!! Arm length is 172.5mm , chainrings are 50/34.
