|Description||NEW! Shimano Dura-Ace R9200 Di2 12 speed groupset.
Built for those who never compromise, Shimano's premium R9200 series moves to 12-speed Di2-only, disc or rim-brake set-up with wireless shifters, faster derailleur operation, larger 54-40T chain rings and 11-34T cassettes.
Series includes a new power meter, SERVO WAVE brake technology and a new line-up of tubeless and tubular wheels.
The launch of new DURA-ACE isn't just the development of an outstanding new groupset, it's also the culmination of a study into the science of speed.
Shimano has delivered its fastest and most precise shifting series, expanding its legacy of innovation while setting a new benchmark in road performance. Every detail, every decision, and every component of the new DURA-ACE R9200 series is engineered to deliver a faster, more reliable, and more intuitive ride experience.
Developed with the Science of Speed design concept, the R9200 series component group features an ultra-efficient 12-speed drivetrain, a reliable wireless cockpit, highly refined ergonomics, new aerodynamic tubeless and tubular wheels, an enhanced brake system, and integrated digital technology engineered for those who never compromise.
The pursuit of perfection doesn't come easy. Developments with the world's best athletes and bicycle component developers meant researching, investigating and analysing product performances in the laboratory and the real-world, leaving no stone unturned to find the science of speed. The result can be broken down into chapters: shifting platform + control interface + brake system + drivetrain system + wheel system.
Shimano has completely revised its Di2 platform to improve shifting speed whilst making the shifter-derailleur connection wireless, and still ensuring absolute reliability.
Shimano's new Di2 platform brings an improved motor design in the derailleurs, which decreases the processing speed, i.e. the moving time between motor and gear mechanisms, and the transmission performance, to enable Shimano's fastest-ever shifting. The result is time saving in fractions of a second but it does result in a 58% decrease in rear derailleur operating time and a 45% decrease in front derailleur operating time.
Absolute reliability is provided by a wired connection where it makes sense. New smaller diameter SD-300 wires connect the Di2 battery (BT-DN300) to the front derailleur (FD-R9250) and rear derailleur (RD-R9250). This single internal battery makes for a simple charging solution and ensures a stable and high voltage connection to the derailleurs, contributing to Shimano's fastest-ever shifting. Absolute reliability is further guaranteed by a high security, fast processing and low power consumption proprietary chip circuit, which significantly decreases the chance of interference from external devices.
Tests show that the BT-DN300 battery, which powers the derailleurs, lasts for 1000 km between charges. The STI shifter buttons are powered by coin-style CR1632 batteries which last for approximately 1.5-2 years of usage. To increase battery capacity further, a fully wired option is also possible, offering a 50% increase in capacity and has practical benefits for riders using new DURA-ACE in combination with an e-bike.
Shimano's new DURA-ACE rear derailleur is no longer just a rear derailleur. It is also the point at which the system is charged (replacing Shimano's SM-BCR2 charger), it provides the connection to the STI shifters via Shimano's proprietary integrated circuit, the ANT+ connection to other 3rd party devices (replacing the EW-WU111 wireless unit), and it replaces the handlebar or in-frame Junction-A (SM-RS910). This results in the RD-R9250 rear derailleur having an integrated design with a hidden charging port, a button for Di2 operations and LED lights, which denote Synchronized Shifting mode, settings mode, or any charging requirements.
