Product description
Hydraulic disc brake calipers can be directly mounted on the frame (flat mount) for a clean low profile design. New dedicated DURA-ACE rotors bring better heat management properties to provide stability in brake performance. With an increased adaptor size, heat transfer through the rotor is decreased and more heat can dissipate through the air. This results in a 30°c reduction in rotor temperature over Shimano’s ICE TECHNOLOGIES FREEZA rotors.
Engineered for the next generation of race bike, DURA-ACE R9100 offers top-tier performance across numerous configurations. Available with either Di2 electronic or mechanical shifting, for the first time, riders now have the option of premium DURA-ACE hydraulic disc brake performance. New Shimano technologies further integrate the DURA-ACE as a system, including a new power meter, while riders further integrate with their bike through new E-Tube wireless connectivity. Shimano’s Rider Tuned philosophy and customization of the bicycle’s function also expands with a wider range drivetrain that now includes intuitive Shimano Synchro Shift control.

Technology
SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEMThe SEIS innovative shift technology is still based on the SHIMANO INDEX SYSTEM (SIS) that has proved its superior gear changing characteristics over the years. The big difference is that in this case, the shifting action is provided for by electronics instead of mechanics. This electronic shifting system has been extensively tested over past two years by several professional riders in all conditions possible, such as rain, mud, low temperatures, cobble stone roads and combinations of all of these at the same time. Shifting is executed by simply pressing the button. No power is needed to shift, which gives important advantages since it is easier now to always keep a tight grip on the handlebar and to keep your concentration on riding instead on shifting. The shift system allows accurate and effortless shifting in difficult circumstances like when you have cold hands or when you are completely exhausted. Furthermore, the shifting performance will never be affected by contaminated or stretched cables since the shifting signal is transferred electronically. The operating buttons work similarly to mechanical Dual Control Levers so you don’t need to re-program your mind for a new system.
E-Tube
E-Tube platform offers optimum flexibility on your bike. E-TUBE transmits interactive signals and power supply to each parts by “Plug & play” connection. E-TUBE is no rust, no stretch, no freeze and it ensures advanced low maintenance. And SM-PCE1 connects between PC and components to update firmware. Digital device stay the latest version with updating firmware for improve function.
Synchro-Shift
SHIMANO Synchronized Shift is a new feature introduced to Shimano´s electronic road groupsets, designed to simplify gear choice and reduce decision making in racing situations. When riding at maximum capacity, decision making can be impaired. The less stresses on a rider and the less decisions a rider has to make, the less mistakes they will make. Therefore SHIMANO Synchronized Shift is designed to choose the next biggest or lowest gear ratio irrespective of whether a gear change needs to be made by the front or rear derailleur.
Two SHIMANO Synchronized Shift modes will be available:
- Full SHIMANO Synchronized Shift: the front derailleur reacts based on the rear derailleur’s shift action. This essentially means that, when activated, there is no need for two separate shifters to control front and rear derailleurs, the two buttons on one shifter will control both derailleurs.
- Semi SHIMANO Synchronized Shift mode: the rear derailleur reacts based on the front derailleur’s shift action, shifting to the next most appropriate rear gear when the rider makes a front shift.
