Perseverance makes a driver to victory Driver - Stay in the fast lane
11-speed drive system of the latest generation:
For the new DURA-ACE 9000 series Shimano has redesigned each component of the system to provide the most innovative component group of all time.
One of the outstanding results of this new development is the variety of translation options, which corresponds to the already known "Rider Tuned" concept. The new 11-speed drive allows each driver, "tune" his bike for each specific intended use by various gradations.
The Dura Ace 11-speed rear derailleur has been completely redesigned and has also thanks to the new, low-friction, polymer coated on trains significantly smoother, faster and smoother shifts. The switching forces are more consistent over the entire switching range of time, so that the forces are nearly identical to the largest and smallest sprockets.
