Shimano just can leave well-enough alone, it seems. Their new, ultra-sleek Dura-Ace FC-9000 11-Speed Crankset with its brilliant 4-arm design not only takes stiffness and light weight to new levels, but uses the same spider for both the compact and standard chainrings. Legendary performance with even more versatility. Way to go, Shimano.

Hollowtech II construction puts structural strength precisely where it's needed
Hollowglide chainrings are durable and lightweight
11-speed compatible only
