Say goodbye to triple cranksets for good! The Shimano Dura-Ace FC-7900 Crankset employs a wide gear range to cover almost any cycling situation you get yourself into. A sleeker, more aerodynamic design than its predecessor saves about 15-grams of weight, and a precise fit between chain and chainring gives you increased power transfer efficiency. The FC-7900 makes super crisp front shifts and its improved bottom bracket seals reduce power-rubbing friction and contamination. Hollow forged thin-walled Hollowtech II crankarms reduce mechanical drag and add extra stiffness to this Shimano crankset.

State-of-the-art engineering makes the Shimano Dura-Ace compact crankset the standard for racing. An aerodymamic design, light weight and high rigidity optimize power transfer.
