Long, fast descents require great confidence in the deceleration performance. The new DURA-ACE brakes create exactly this confidence with their new design with symmetrically arranged double joint, by reducing friction and thus increasing efficiency and controllability through the double bearing and the two rotary axes. In combination with the new low-friction BC-9000 brake cables, the DURA-ACE brakes ensure smooth, smooth but powerful braking processes with excellent modulation.
Shimano Dura Ace - For highest expectations! The Dura Ace is Shimano's lightest, most ergonomic and most precise component group ever.

The additional 11th gear and numerous other improvements allow for truly dominant performance. With Dura Ace you win.
