What year is Dura-Ace 7800?

A 10th sprocket might have been the headline feature of Shimano’s new top-line groupset, but the Japanese company did far more than shift up a gear when it launched Dura-Ace 7800 in 2004.
Does Dura-Ace shift better than Ultegra?

Is Shimano Dura Ace worth it?
Two years, over 10,000 miles, one conclusion: Shimano’s Dura-Ace 9000 mechanical group is the best human-powered drivetrain the world has ever seen. If you’re a weight-weenie, look to SRAM, home of the best weight/cost ratio in the industry.

Will 10 speed shifter work with 11 speed cassette?
