SHIMANO Dura-Ace Di2 Road Groupset R9270

Description

Shimano Dura-Ace Di2 Road Bike Groupset R9270 2×12

With the components of the 9200 Dura-Ace series, Shimano offers the very best currently available on the market. The Japanese company’s many years of experience are evident in every detail—in terms of functionality, durability, and weight. As a result, Shimano’s top-of-the-line groupset is revolutionizing Di2 components. Wired technology with a new, exclusively developed transmission protocol now delivers the fastest shifting in the cycling industry. To make the rear and front derailleurs as compact and aerodynamic as possible, these components are connected to the new BT-DN300 internal battery via an E-Tube cable.

Dura Ace Di2 Shift Lever ST-R9270 and BR-R9270 Flat Mount Disc Brake Set
A single press of a button—and gears are shifted quickly and precisely. The precise actuation point of the levers ensures that shifting occurs only when the rider intentionally makes the movement. There is no risk of accidental activation. The wireless chip features low power consumption—the CR1632 battery lasts over 1.5 years. The system is fully configurable in the Shimano E-Tube app, allowing you to tailor the shifting logic to your preferences, including shift speed, full or semi-synchronous shifting mode, and button assignments on the shifters.
During braking, SERVO WAVE technology ensures optimal bike control in every situation, offering excellent modulation and braking power. Ergonomics have also been significantly improved—the finger grooves are better contoured, and the rounded levers sit securely in the hand even on long descents. Grip width can be individually adjusted. The lighter BR-R9270 caliper offers a wider pad spacing, reduces noise, and the new monoblock design achieves peak braking performance. New bleeding technology simplifies maintenance.

FC-R9200 2x Crankset
The Dura-Ace FC-R9200 crankset not only transfers pedaling power to the drivetrain, but its high stiffness also ensures exceptionally fast and precise shifting. Optimized chainrings improve shifting accuracy. To keep weight down, Shimano uses the proven Hollowtech II crankarm design. A wide selection of crankarm lengths and chainring options ensures the perfect configuration for every rider and every terrain.

RD-R9250 Di2 Shadow+ Rear Derailleur
The compact Dura-Ace 9250 rear derailleur ensures lightning-fast and precise shifting. Thanks to its low profile and Shimano Shadow+ technology, gears shift quickly, quietly, and smoothly even under heavy load. Despite its slim dimensions, the derailleur features a battery charging port and a wireless mode button. A single cage length accommodates cassettes ranging from 11-28 to 11-34 teeth, increasing the component’s versatility. The carbon fiber cage minimizes weight.

FD-R9250 Di2 Front Derailleur
The Dura-Ace 9250 front derailleur is a major step forward. It weighs less than 100 g, has a compact design that reduces air resistance, and offers 45% more precise shifting.

BT-DN300 Internal Battery
A modern battery built into the seatpost or head tube. Internal cable routing ensures a clean look and minimizes air resistance. The battery remains in the frame during charging.

CS-R9200 Cassette
Shimano Hyperglide+ cassettes deliver smooth shifting across the entire gear range. Thanks to longer cogs and a 12-speed design, shifting remains smooth even under maximum effort. The use of titanium in the smaller sprockets helps keep the weight low. Cassettes are compatible with earlier 11-speed Road freewheels.

Dura Ace | XTR CN-M9100 12-speed chain
The CN-M9100 chain is distinguished by its exceptionally smooth and quiet operation (4 dB quieter). The chrome-plated surface and SIL-TEC coating ensure a long service life despite the narrower outer width.
