SHIMANO Dura Ace complete set R9100 Disc | 2x 11-speed
Complete set of the mechanical Shimano High End road bike group for disc brakes
This Dura Ace Complete Set is ideal for riders looking for the best low-weight drive and shifting performance. The Dura Ace Group offers Shimano's usual high gearshift precision and speed.
Dual Control shifter / brakes
ST-R9120 / BR-R9170 Flat Mount
Like its mechanical counterpart, a shorter stroke, the R9120 series dual-control lever for hydraulic disc brakes offers a wider range with longer range, and facilitates gear shifts for quick and intuitive shifting in all situations. The new disc brakes also allow a higher and better metered braking force in all weather conditions.
Other enhancements include the new cover material and the convenient ergonomic shape of the lever for added grip. With their narrower and more elegant croissants, the 11-speed ST-R9120 levers offer improved ergonomics that not only increase comfort but also enhance control.
SM-RT900 Center-Lock | IceTech FREEZA
Shimano Ice-Tech is a cooling technology that provides maximum consistent braking performance. The brake disc is characterized by its three-layer sandwich construction of stainless steel flanks with an aluminum core and offers significantly improved heat dissipation. As a result, the temperature can be lowered by around 100 ° C.
The new Dura Ace FREEZA rotors also have aluminum cooling fins, which can reduce the system temperature by an additional 50 ° C due to their increased surface area.
For quick and easy installation, secure grip and a clean and compact look, the discs are equipped with a Center-Lock mount .
The new Dura Ace crankset is characterized by a very high switching performance. The gear changes take place with high precision.
This is achieved through its wider HOLLOWTECH II arm and a reinforced outer chainring on its unique asymmetric spider construction with four arms. In terms of rigidity and lightness, the new R9100 cranks meet the highest standards.
FC-R9100, gradation: 50-34 teeth | Crank length 170, 172.5 or 175 mm
FC-R9100, gradation: 52-36 teeth | Crank length 170, 172.5 or 175 mm
FC-R9100, grading: 53-39 teeth | Crank length 170, 172.5 or 175 mm
RD-R9100 short cage
The 11-speed DURA-ACE rear derailleur has been equipped with low-friction polymer-coated traction for easier, faster operation. This new rear derailleur is also equipped for direct mounting, providing a stiffer basis for improved shifting and minimizing the likelihood of collision damage to the frame.
The front derailleur cable guide has been adapted to further reduce the force when shifting. The precise and easy adjustment of the derailleur offers more traction options and an integrated adjustment of the tension. With its optimized gear ratio in combination with the ST-R9100 switching | The new Dura Ace front derailleur provides brake levers and coated features for both shorter lever travel and reduced shifting forces.
Silky smooth gear changes are the feature of every Dura Ace group. The cassettes make a significant contribution to this superior feel. With tooth shapes and shifting aids perfectly matched to the chain, a gear change can be described as almost a sliding of the chain between different pinions. An intelligent material mix of aluminum, steel and titanium increases the life, while reducing the weight of the cassette.
The use of a high-quality steel alloy and the adaptation of each individual inner and outer plates allows excellent shift quality and smoothness. Furthermore, the chain was designed directional and provides mud and dirt especially little attack surface.
High-quality and multi-sealed bearings complete the overall package of Dura Ace switching groups. The bearings are made to all common standards and shine with the typical Shimano silky smooth running.
Weight of the complete group: from 2278g (without bottom bracket and without brake discs)
