Ultegra Di2 2×11-speed STI Dual Control ST-R8070 Set
In addition to the benefits of the ST-R8050, the ST-R8070 offers greater rider control in all conditions, due to the hydraulic disc brake. With its minimized bracket size, the ST-R8070 feels great on the palms and improves the ergonomics.
Everything you need to make your ride distinctively yours: Shimano Ultegra Di2 2×11-speed STI Dual Contral ST-R8070 Set for Hydraulic Disc Brakes The new Ultegra R8000 series is taking our rider-tuned philosophy to the next level, with an extensive range of components for mechanical shifting, electronic shifting (Di2) and time trial / triathlon.
The new Di2 lever can operate with the recently released full or semi Synchronized Shifting function (with the BT-BN110 battery), giving riders the option to make automatic shifts from the front (full) or rear (semi) derailleurs. This means that you could set, for example, both left shifters to move up through the drivetrain and both right shifters to move down through the drivetrain. As well as this the shifters have more defined click feeling to offer quick and precise shifting with gloves. Following the design of the ‘secret’ Dura-Ace Di2 shifter buttons, the new Ultegra ST-R8070 hydraulic Di2 and ST-R8050 rim brake Di2 levers also include the top-of-the-hoods buttons for remote shifting, which can be programmed to shift gear or to control ancillary devices such as compatible computers or lights. All shift levers or buttons can also operate multi-shift which, like the top button and Synchronized Shift features, are customisable in the E-TUBE app for phones, tablets or PCs. The app not only allows you to customize functions and operations as you please, but also allows you to keep all units up-to-date with the latest firmware and run error checks to pinpoint and solve abnormalities.

Technology? SEIS SHIMANO ELECTRONIC INTELLIGENT SYSTEM The 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.
