Shimano Dura Ace groupset R9100 Disc | 2x11-speed
Complete the mechanical Shimano High End road group for disc brakes
This Dura Ace complete set is ideal for drivers who are looking for best drive and switching performance with low weight. The Dura Ace group has the Shimano's usual high Schaltpräzision- and speed.
Dual Control shifter / brake
ST-R9120 / R9170-BR flatmount
The Dual Control lever for hydraulic disc brakes of the R9120 series, like its mechanical counterpart, a shorter stroke, a larger setting with more range and facilitates switching operations for quick and intuitive switching in all situations. The new disc brakes also allow a higher and better braking control force in all weather conditions.
Other enhancements include the new material of the cover and the comfortable ergonomic shape of the lever for more support. With its narrow and elegant croissant, the 11-ST-R9120 lever to improved ergonomics, which leads not only to increased comfort, but also to improved control.
SM-RT900 Center Lock | IceTech Freeza
Shimano Ice-Tech is a cooling technology that ensures maximum consistent braking performance. The disc is characterized by its three-layer sandwich construction made of stainless steel edges with an aluminum core and has a substantially improved heat dissipation. This makes it possible to reduce the temperature to 100 C.
The new Dura Ace Freeza rotors also have aluminum fins, which can reduce the system temperature by their increased surface area by another 50 C.
For fast and easy installation, secure grip and a clean and compact appearance, the wheels are equipped with a center-lock receptacle.
The new Dura Ace crankset is characterized by a very high switching performance. The gearshifts are doing with high precision.
This is achieved by its broader HOLLOWTECH II-arm and a reinforced outer chainring to its unique asymmetrical Spider-construction with four arms. In terms of stiffness and lightness, the new R9100 cranks highest standards to meet.

RD-R9100 short cage
The 11-speed Dura-Ace rear derailleur has been fitted with low-friction polymer coated trains to enable a simpler, faster operation. This new rear derailleur is also equipped for the direct mounting, which provides a more rigid base for improved shifting and minimizes the likelihood of damage to the frame due to collisions.
The derailleur cable routing has been adapted in order to reduce the force when switching on. The precise and easy adjustment of the derailleur offers more Zugführungsoptionen and an integrated adjustment of the tension. With its optimized transmission ratio in combination with the ST-R9100 Switching | Brake lever and the coated coatings makes the new Dura Ace derailleur both shorter lever paths as well as for reduced shifting forces.
Silky smooth gear changes are characteristic of each Dura Ace group. The cassette control for this überragendem shift feel in a substantial part. Designed exclusively for the chain tooth shapes and switching aids a gear change can be described almost as a sliding of the chain between different gears. An intelligent mix of materials of aluminum, steel and titanium increases the service life, but at the same time reduces the weight of the cassette.
The use of high-quality steel alloy and customizing each inner and outer plates enables excellent shift quality and smoothness. Furthermore, the chain was designed directional and provides mud and dirt especially little contact surface.
High quality and multiple sealed bearings round out the overall package of the Dura Ace rear groups. Bearings are in all common standards and shine with the typical Shimano smooth running.
Weight of the complete group: from 2548g
