What is the best Dura Ace
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.
When did Dura Ace 9000 come out

Does Shimano make carbon cranks
By using this technology, Shimano developed a crankset that combines the best of both materials. The aluminum frame ensures a stiff set-up for optimal power transfer while using carbon saves weight. Weight of this crankset (including bottom bracket) is 715 grams.Jul 4, 2008
When did Dura Ace 7800 come out
2004A 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.
Is Shimano Dura Ace better than Ultegra
Although Dura Ace is considered to Shimano's out-and-out performance groupset, surprisingly, Ultegra is generally deemed to be much more versatile, mainly because of the lower range of gears that it offers. While Ultegra cassettes go all the way up to 34 teeth, Dura Ace cassettes only go up to 30 teeth.
Is it worth upgrading from Ultegra to Dura-Ace
The quality of the Ultegra and Dura-Ace components is almost identical, but Dura-Ace is slightly lighter. If you're a competitive climber to whom a few grams of weight savings makes a big difference, then Dura-Ace would be justified.
Are Ultegra chainrings interchangeable
The current Ultegra chain rings are in fact physically compatible with the 105.
Are chainrings interchangeable
Largely speaking, yes. As long as your attempting to replace them with a chainring(s) designed to work with your chainset. Your cranks will have a specific bolt layout or fitment spec so you can't just fit a BMX chainring to your triathlon bike.
Are Dura Ace crankset carbon
At Eurobike Shimano introduced a carbon fiber Dura-Ace crankset. The FC-7800C has an aluminium core to realize a lightweight yet very rigid construction. By using this technology, Shimano developed a crank set that combines the best of both materials.Mar 7, 2008
Are Dura-Ace components good
Dave Lawrence, Shimano's Road Product Manager explains, “Dura-Ace is Shimano's no compromise, highest performance, and lightest-weight road groupset.” For riders competing at the sharp end, who need every advantage possible, Dura-Ace is the only option. It's what top pros choose when running Shimano on their own bikes.
