• Dura Ace Di2 ST-R9270/BR-R9270 2 x 12 Dual Control Shift/Brake Lever: The new ergonomics of the DURA-ACE ST-R9270 Dual Control shift/brake levers offer a new level of comfort and control for racing cyclists. With faster wireless switching capability and even more precise brake force adjustment, DURA-ACE sets new standards in performance. Now equipped with SERVOWAVE brake technology, the DURA-ACE ST-R9270 brake lever offers a level of control and control that is second to none. Wireless shifting ensures a clear view of the bike and allows for remarkably fast and precise gear changes. All of this is integrated into a dual shift/brake lever that, thanks to the use of the latest generation materials, is lightweight and ergonomic, ensuring optimal comfort and control even in difficult conditions. Thanks to the brand new design, the DURA-ACE BR-R9270 hydraulic brake caliper is more compact than ever. The monocoque construction ensures low weight and high rigidity, demonstrating that high performance is possible even with compact dimensions. With the all-new monocoque construction, the pinnacle of high braking performance has now been achieved. The lighter BR-R9270 brake caliper offers wider pad spacing and reduces noise levels. Finally, a new venting process also makes maintenance easier than ever.
• Dura-Ace Di2 RD-R9250 Rear Derailleur: With the fastest gear changes in the largest DURA-ACE gear ratio to date, Shimano's RD-R9250 rear derailleur opens up the possibility of victory or personal best opportunities. The DURA-ACE RD-R9250 rear derailleur features an integrated charging port and wireless signal transmission, enabling super-fast and precise shifting. With a single cage length, cassette shifting goes from 11-28 to 11-34 teeth, further enhancing the versatility of the world's best road bike groupset.
• Dura Ace Di2 FD-R9250 Front Derailleur: Despite its smaller and lighter construction, the DURA-ACE FD-R9250 offers the fastest front derailleur shifting on the market. Faster shifting is now even faster with the DURA-ACE FD-R9250 front derailleur. Compared to the FD-R9150, currently the fastest front derailleur on the market, the new design weighing less than 100 grams ensures 45% faster gear changes on the front. The front contact surface of the FD-R9250 has also been reduced to reduce wind resistance.
• Dura Ace FC-R9200 Crankset: As the heart of the bike, the DURA-ACE FC-R9200 crankset ensures no pedal power is lost. Hollow crankarms and hollow chainrings minimize weight, while maximizing stiffness and shifting precision.
• The DURA-ACE FC-R9200 crankset: offers two essential functions: transmitting pedal force into drive energy and ensuring extremely fast and precise shifting processes at the front. With lightweight HOLLOWTECH II cranksets and premium Shimano chainrings, the FC-R9200 crankset ensures reliable functionality and performance. The FC-R9200 is also available with shorter cranksets to offer a suitable option for every type of rider.
• Dura Ace CS-R9200 Cassette: The seamless shifting of the DURA-ACE R9200 12-speed cassette allows riders to fully focus on climbs, sprints, and pushing their limits without having to worry about the next gear change. Larger cogs ensure greater efficiency and are compatible with Shimano 11- and 12-speed freehub bodies. HYPERGLIDE+ cassettes set new standards for off-road shifting with smooth shifting across the entire gear range. It's time for this technology to be used on road bikes as well. Even under maximum effort on climbs or during the sprint to the finish line, riders no longer have to shy away from shifting. The DURA-ACE R9250 drivetrain ensures maximum efficiency in all gears thanks to larger cogs and is compatible with existing 11-speed freehub bodies. Despite their expansion to 12 gears and without causing additional weight, the DURA-ACE CS-R9200 cassettes set new standards in road bike gear shifting systems.
• CN-M9100 Chain: The M9100 chain was developed for the pioneering Shimano groupset (12-speed). Thanks to an expanded inner plate, it offers improved chain retention. The new chain is suitable for QUICK-LINK assembly and is SIL-TEC treated for increased durability in off-road conditions.
• RT-MT900 Centerlock Brake Disc: The Shimano RT-MT900 brake disc defines the highest braking performance and offers excellent stopping power even with an aggressive riding style. ICE TECHNOLOGIES FREEZA brake discs dissipate heat to ensure braking performance is not compromised even on long descents. With the Shimano Centerlock mounting system, brake discs can be mounted quickly and easily thanks to the lock ring design.
• BT-DN300 Di2 Battery: The new DN300 battery features the same waterproof design that Di2 users have loved for years. Now with 3 connections, it offers stable performance for Shimano 12-speed road bike front and rear derailleurs (when a fully wired version is selected). With the same dimensions as the previous model, the flat-mount DN300 battery can be integrated into the seatpost or frame for a clean look. Now with 3 connections, the DN300 simplifies cable routing to the front and rear derailleurs and offers seamless performance at all times. The third connection is for those who want to keep the option of a wired version of Shimano's 12-speed Di2 systems open.
• EW-EC300 Di2 Charging Cable: The new EC300 charging connector is specifically designed for Shimano 12-speed Di2 road bike components. It can be connected to the derailleur mount as well as to Shimano Power Meter cranksets. The new derailleur-mounted cable is more economical than previous charging cables and can also be used to charge Shimano power meter cranksets.
