Most advanced component group of all time: Shimano Dura Ace 11-speed Di2 Rear Derailleur RD-R9150 SS

With the introduction of DURA-ACE R9100, Shimano has reestablished the new benchmark for road performance by improving each component and incorporating its newest technologies. DURA-ACE R9100 delivers unparalleled performance, highly-refined ergonomics and immense customization to maximize every rider’s potential.

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.

Front (FD-R9150) and rear derailleurs (RD-R9150) incorporate these new cockpit functions. Both electronic derailleurs are compact and designed to protect the shifting operation in the event of a crash. The low profile of the rear derailleur also comes with SHIMANO SHADOW RD technology, positioning the derailleur further below the functioning sprocket.

Technology

Shimano Shadow RD

The mechanism rear derailleur, SHIMANO SHADOW RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.

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.

DANGER
- Use the specified charging cable when charging the battery. Using any other items may lead to fire, overheating, leakage, or damage to the connected PC.
- Prevent the charging cable from getting wet, and do not touch or hold it when it is wet or when your hands are wet. Failure to do so may result in problems with operation or electric shock.
- Use an AC adapter with a USB port with a voltage of 5.0 V DC and a current of at least 1.0 A DC. If you use an adapter with a current rating of less than 1.0 A, the AC adapter may heat up and cause fire, smoking, overheating, damage, electric shock, or burns.
- Do not heat the battery or expose it to fire. Failure to do so may result in the battery burning or bursting.
- Do not use or leave the battery in hot or humid places where the battery may be exposed to direct sunlight, in a closed vehicle on a hot day, or near a heater. Failure to do so may result in leakage, overheating, or bursting, which may cause fire, burns, or other injuries.
- Do not deform, modify, or disassemble the battery. Also, do not directly apply solder to the battery terminals. Failure to do so may result in leakage, overheating, or bursting, which may cause fire, burns, or other injuries.
- Do not touch the metal terminals with metal objects such as hairpins. Failure to do so may result in short circuits, overheating, burns, or other injuries.

WARNING
- Do not disassemble or modify the product. This may cause the product to malfunction, and you may fall unexpectedly and be seriously injured.
- Always grasp the cable plug when connecting or disconnecting the USB cable or charging cable. Failure to do so may result in fire or electric shock.
- If the following symptoms occur, stop using the device and contact the place of purchase. Fire or electric shock may occur.
- If pungent smoke comes out of the AC plug or the plug is heating up. There may be a bad connection inside the AC plug.
- If there is thunder during charging with an AC adapter with a USB port, do not touch the device, bicycle, or AC adapter. Electric shock may occur due to lightning.
- Do not use a USB hub to connect the cable to the PC's USB port. Charging failure or fire due to overheating may occur.
- Be careful not to damage the charging cable. Do not damage it, modify it, bend it forcibly, twist or stretch it, place it near hot objects, place heavy objects on it, or tie it tightly together. Using it in a damaged state may result in fire, electric shock, or short circuit.
- If the battery does not fully charge in 4 hours of charging, stop charging. Failure to do so may result in fire, bursting, ignition, or overheating.
- Do not immerse the product in fresh or salt water, and prevent the terminals from getting wet. Failure to do so may result in fire, bursting, ignition, or overheating.
- Do not subject the product to strong impact or throw it. Failure to do so may result in bursting, overheating, or problems during operation.
- Do not use the battery if it shows liquid leakage, discoloration, deformation, or other unusual signs. Failure to do so may result in bursting, overheating, or problems during operation.
- Clean the chain and QUICK-LINK regularly with a suitable chain cleaner. Maintenance intervals depend on usage and riding conditions. Never use alkali or acid-based solvents such as rust removers. If such a solvent is used, the chain or QUICK-LINK may break and cause serious injury.
- Check that the chain is not damaged (deformation or cracking), skipping, or showing any other abnormalities such as erratic shifting. If any problems occur, consult the place of purchase or a distributor. The chain may break and you may fall.

CAUTION
- Store in a safe place out of the reach of small children to prevent accidental ingestion.
