Shimano Dura-Ace 7900 Crankset

Shimano Dura Ace 7900 10-Speed Crankset:
Shimano's Hollowtech II crankset is an engineering feat. The rings are independently constructed and machined down to perfection. The two pieces are then epoxied together for maximum strength at a fraction of the weight. The aerodynamically shaped crankset offers additional time-savings, while accommodating the highest rigidity for optimal power transfer.
