The Dura Ace group set from Shimano once again sets new standards for performance in the road cycling world with its 9000 series. The Dura Ace 9000 drivetrain is powered by the redesigned FC 9000 crankset. By eliminating one of the spider arms, Shimano was actually able to reduce the weight without sacrificing stiffness and durability and also incorporated a new chain catcher design in order to reduce chain drop. The RD 9000 rear derailleur features a redesigned rear system and spring mechanism and is lighter and shorter than the RD 7900. The RD 9000 rear derailleur and FD 9000 retain the flawless, smooth shifting characteristic that Shimano’s Dura Ace group is known for and has improved shifting performance under load, bringing it within range of Dura Ace Di2 level. Special cables with a low friction coating and new nosed ferrules provide a claimed decrease in shifting effort of up to 43% for the front derailleur and 47% for the rear. The ST 9000 STI shifter lever shifts up to 3 gears at a time as opposed to the ST 7900 lever and feature completely redesigned lever body that is more ergonomic and more comfortable. The Dura Ace BR 9000 brakes also benefit from low friction cables that improve barking power by 20%. Overall, the Dura Ace 9000 corrects and improves on the shortcomings of Dura Ace 7900 and sets a new standard for road component performance.

Comments about Shimano Dura-Ace 9000 STI Build Kit:

I bought this for a friend and he seems to love it. Only draw back is that it appears to have worn out easily.
