Shimano America Dura Ace FC-7900 Crankset

The Shimano Dura-Ace FC-7950 Crankset has only one thing on its mind: speed. Oh, and power transfer ... and aerodynamics. Regardless, you'll laugh as you cruise by the Freds on the climb, and as you throw the hammer down past the leaders on the downhill.

Bottom Line: Compact for climbing, stiff, light, and aero for speed.

Sure have, a bit. Crazy stiff cranks! A little bird told me they're coming out with some different material cranksets for DA in the fairly near future. These are great cranks though!
