The Dura-Ace Group-set has improved braking operation along with stylish and ergonomic Dual Control STI lever system. Ten speed gearing is a must for the serious cyclist; the double Hollowtech II crankset with integrated bottom bracket is a light, strong piece of art with smooth lines and in seven different lengths.
The Dura-Ace front and rear gears are quick and accurate, 9 or 10 speed compatible and very light. 10 speed Cassette sprockets are compatible with the 9 speed freehubs due to the narrowing of the sprockets and treatment of the titanium to strengthen them upto 30% more for durability.
The Dura-Ace hub set is super lightweight, 10 speed compatible only and smooth rolling. The chain is made from zinc-alloy which is light and strong as is the bottom bracket which has minimal bearing interface for smoother rolling. Dura-Ace Pedals are low profile and have a platform design for improved foot-pedal stability and wide bearing placement for enhanced load distribution.
