Shimano 105 di2 rear derailleur shadow rd-r7150 12-speed

Product Description Shimano 105 Di2 RD-R9150 Rear Derailleur - High-tech centre with shadow design The RD-R7150 Di2 is the first electronic rear derailleur from the Shimano 105 series. Due to its generous total capacity of 41 teeth, you can shift 12-speed cassettes with a largest sprocket of 34 to 36 teeth, which is also a novelty in road cycling. The compact unit, which only weighs about 40 grams more than the Ultegra model due to its high aluminium content, contains a lot of high-tech features: the wireless unit for wireless communication with the STIs, the charging port, which you can use to easily recharge your shifters and derailleurs with the help of the matching charging cable, and a function button. You can use it to adjust the rear derailleur, check the battery status, change the shift mode from manual to Synchro and Semi-Synchro Shift or establish a Bluetooth connection to a bike computer or smartphone. An LED display helps you to do this. The rear derailleur is connected to the battery via a cable, from which a cable also runs to the front derailleur. It impresses with its fast, precise shifting processes as well as with its Flat Shadow design, which optimises the shifting behaviour and prevents damage.

In addition, the single preload ensures that the rear derailleur does not hit the chain stay even on very uneven ground. All of this contributes to a quiet, clean-operating gearshift. Digital Integrated Intelligence (Di2) Di2 systems are the electronic shifting systems from Shimano. They are based on the SEIS, the Shimano Electronic Intelligent System, which takes over the index shifting function from the mechanical components, only via power cables or radio signals and not via a Bowden cable. Shifting is done by simply pressing a button. This has the advantage that no great effort is required, your concentration on the ride is not disturbed and operation is easy even with cold hands. In addition, the electronic gear changes are very fast and highly precise. There is also no risk of a defective circuit due to dirty cables or other problems. You can adjust individual settings via the E-Tube Project, such as adjusting the shifting speed, the number of shifting operations per button press or the Synchro or Semi-Synchro shifting function. Shimano offers an app for this purpose. Gear maintenance and firmware updates are also done via E-Tube, with the bike connected to a PC running the appropriate E-Tube software for more extensive workshop work. D-Fly Shimano D-Fly is a Near Field Communication (NFC) network that allows Shimano E-Tube electronic components (Di2, STEPS) and smartphones or compatible bike computers to communicate with each other. For example, it is possible to view information about the components on the display or to track power meter data. Shimano provides the E-Tube Ride app just for this purpose. D-Fly is compatible with ANT+, ANT as well as Bluetooth. Network partners include Garmin, Wahoo, Sigma and Cateye for Di2 components and Garmin and Sigma for STEPS components. Shimano Synchronized Shift Shimano's synchronised shifting function is a shifting mode that automatically matches the Di2 rear derailleur and Di2 front derailleur. It is activated either via the E-Tube platform or via the rear derailleurs with a function button. Synchro Shift means that the front derailleur automatically selects a suitable gear depending on the position of the rear derailleur, while Semi-Synchro Shift means that a suitable rear derailleur position is automatically set when you operate the front derailleur. This gives you the advantage that you only have to concentrate on one side of the shifting process and are not thrown off-rhythm by sudden unfavourable changes to the gear ratio. Models:long: Max.
