Built for the rider who never compromises, Shimano's new DURA-ACE R9200 series enters the 12-speed era, offering only Di2 electronic shifting specifications with wireless shifting grips for faster shifting response action, new larger 54-40T sprocket blades and 11-34T flywheels The new R9200 series kit also includes a new power meter sprocket, SERVO WAVE brake technology and a full range of wheelsets.

Shimano continues its tradition of innovation with the introduction of the new DURA-ACE R9200 Series, which not only continues its tradition of innovation, but also sets a new benchmark for performance in its road kits. Every detail, every decision and every part of the new DURA-ACE R9200 series is designed to deliver a faster, more reliable and superior riding experience.
Developed using the Science of Speed design philosophy, the DURA-ACE R9200 series includes an efficient 12-speed drive system, reliable wireless components, highly optimized ergonomics, new pneumatic vacuum and tube tire wheelsets, enhanced braking systems and built-in integrated electronics to meet the needs of riders who are committed to performance without compromise.

The quest for perfection is not an easy one. The R&D staff constantly works in depth with World Tour pro teams and riders, which means that the investigation and analysis of new product performance is achieved based on a close combination of laboratory and real riding environments, and we leave no stone unturned in the pursuit of a whole new level of Science of Speed (SOS). The result of the research and development can be divided into the following links: gearing platform + control interface + brake system + drive system + wheelset system.
Let's take a look at each of the improvements one by one.

Shifter platform: faster speed, consistent reliability, highly integrated and integrated design

Control interface: excellent ergonomic design, clean and tidy control area, personalization

As high-level professional cyclists have continued to demand changes to their bike settings and riding positions in recent years, Shimano has worked with these pros to develop a bike that meets the needs of different types of racers for climbing, sprinting and time trials, and Shimano has achieved an excellent ergonomic design for comfort, cleanliness and aerodynamics. The Shimano has achieved a clever balance between superior ergonomics for comfort, clean looks and aerodynamics.

The wireless link shifter allows for easier installation and saves the frame handlebar from having to set up wire ports for wired shifting. With a full internal cable routing design, a very clean control area is achieved.

Available with wire ports are minimally designed external shift buttons, Shimano sprint buttons (SW-R801-S) or climb buttons (SW-R801-T) that can be installed with the clamp ring or integrated into the handlebar via specific ports, such as the new PRO Vibe EVO handlebar. These new, more compact control options can be mounted either on the handlebar with a 100mm Di2 cable (SW-R801-S sprint button) or on the top of the handlebar with a 260mm Di2 cable (SW-R801-T climb button).

Professional riders often want to get from the start to the finish of a race at a faster pace. To achieve this most immediate goal, Shimano has optimized drive ratios, gear shifts and power meters throughout the drive system to enhance drive system performance.

The new DURA-ACE 12-speed HYPERGLIDE+ flywheel retains the 11T tooth count of the smallest flywheel, but optimizes the optimal shift sweet spot between the 6th, 7th and 8th flywheels to maintain the same smooth shifting during Shimano's flywheel movement.

Thanks to the combination of the flywheel's cleverly angled chamfered profile and fast, smooth shifting, smoother shifts are possible, even under high pedaling loads, both up and down.

The result is that there is no longer any need to stop accelerating or to reduce pedaling power when shifting. Thanks to the DURA-ACE flywheel with HYPERGLIDE+ technology, riders can focus their power entirely on pedaling and achieve faster shifts for smoother and better speed translation.

The new R9200 kit has two DURA-ACE HYPERGLIDE+ flywheel options: the new DURA-ACE 11-34T flywheel is better suited for steep climbs. The flywheel design has a new tower base spline adaptation mode, backwards compatible with the DURA-ACE R9100 11-speed tower base, which means that the new DURA-ACE R9200 parts can be used with the previous R9100 series wheelsets.
In addition to offering a new DURA-ACE R9200 flywheel (11-34T) with a more modern race style, the larger 54-40T sprocket blade option offers higher drive efficiency compared to the previous sprocket blade and helps professional riders cope with the ever-increasing speed demands.

Faster shifting was talked about above, but there's more to say. The shifting action of the new DURA-ACE R9200 kit is operated by a lighter, smaller and cleaner Di2 front derailleur (FD-R9250) and a more advanced SHIMANO hidden rear derailleur (RD-R9250). The front derailleur has a third less windward area, drops in weight to 96g, and provides more room for 50 to 55T sprocket blades.

The new DURA-ACE R9200 drive system cranks offer two versions of options, the option with built-in integrated power meter (FC-R9200-P) and the standard sprocket option (FC-R9200), and of course many different size specifications. Both sprockets feature HOLLOWTECH II (second generation hollow technology) and are available in 50-34T, 52-36T and the new 54-40T sprocket blade combination with crank lengths from 160mm to 177.5mm and Q-Factor values of 148mm. the power meter sprocket version is compatible with Bluetooth and ANT+ communication modes for use as data transfer. The power meter can be used for more than 300 hours on a full charge and further enhances the accuracy of the power meter.

Braking system: extremely superior braking power, quieter system, easy maintenance

Speed depends on how you control it. The winning or losing moment can come at any turn, and superior braking will make or break it.

Shimano's new DURA-ACE brakes give you finer control in more intense, faster, and more aggressive corner-filled road races. By incorporating SERVO WAVE technology from Shimano's mountain and Gravel brakes into the new DURA-ACE R9200 brakes, riders get shorter brake travel and more direct contact between the brake clamps and discs, resulting in smoother braking and easier adjustment, allowing you to corner more confidently on curvy roads. The brakes are smoother and easier to adjust, allowing you to corner more confidently on curvy roads while maintaining a faster speed.

Maintenance of the brake system is likewise improved. Thanks to the separate oiling hole and oiling screw, you can achieve oiling without removing the clamp (BR-R9270) from the frame. The new funnel and clamp pads also help improve the oiling process.
