SHIMANO DURA ACE DI2 R9270 HYDRAULIC DISC BRAKES GROUPSET

SHIMANO Dura Ace Di2 road bike group set R9270 hydraulic disc brakes 2x12

With the components of the 9200 Dura Ace series, Shimano offers you the best that is currently available on the market. You can see the Japanese company's years of experience in every detail. Whether functionality, durability or weight, top values are achieved everywhere. With this top group set, Shimano is revolutionizing Di2 components. The wireless technology with the exclusively developed transmission protocol guarantees you the fastest shifting operations that are currently possible in the bicycle sector. To make the rear derailleur and front derailleur as compact and streamlined as possible, these components are still connected to the new internal BT-DN300 battery via an E-Tube cable.

Dura Ace Di2 shift lever ST-R9270 set and BR-R9270 flat mount disc brake set
One push of a button and the gears are engaged quickly and reliably. The precise pressure point of the levers ensures that the gear changes are only triggered when the rider consciously shifts gears. Accidental operation is not to be feared. The wireless chip also scores points for its low energy consumption. The CR1632 button cell has a service life of over 1.5 years. This system is fully customizable with the Shimano E-Tube app. This allows the shifting logic to be adapted to the rider's preferences. Among other things, the shifting speed can be set, a fully or semi-synchronous shifting mode can be selected and the program buttons on the lever can be assigned specific functions.
When braking, SERVO WAVE technology gives you optimum control over your bike at all times. This offers unparalleled modulation and sufficient power. But it's not just the inner values that are impressive. The ergonomics have also been significantly improved. The grip recess is better shaped and the rounded brake levers lie securely under your fingers even on long descents. The grip width can also be individually adjusted. The lighter BR-R9270 brake caliper offers greater pad spacing and reduces the noise level. In addition, the brand new monobloc design has reached the peak of high braking performance. Finally, a new bleeding technology makes maintenance easier than ever before.

FC-R9200 2x crankset
The Dura-Ace FC-R9200 crank not only converts your pedal power into propulsion, with its high rigidity it also ensures extremely fast and precise shifting. The high shifting precision is supported by the optimized chainring design. In order to keep the weight low, the Japanese continue to rely on the proven Hollowtech II design of the crank arms. A large selection of crank arm lengths and chainring options ensures that the right crank is available for every type of rider and every terrain.

RD-R9250 Di2 Shadow+ rear derailleur
The compact Dura-Ace 9250 rear derailleur delivers lightning-fast yet precise shifting. Even under medium and high loads, thanks to the low profile design and Shimano Shadow+ technology, gears are changed quickly and without any major noise development. There is no noisy cracking or rattling with these high-tech components! Despite its slim dimensions, the rear derailleur houses the battery charging port and the wireless mode button. With just one cage length, the rear derailleur shifts on cassettes from 11-28 teeth to 11-34 teeth, thus increasing the versatility of the top Japanese component group. The carbon composite rear derailleur cage ensures maximum weight reduction.

FD-R9250 Di2 front derailleur
In developing the Dura-Ace 9250 front derailleur, Shimano has taken not just a small step but a major leap forward. Weighing less than 100 grams, the FD-R9250 is not only considerably lighter, it also impresses with its much more compact design, which reduces air resistance with its small frontal contact surface. A lot has also changed in terms of the internal values. The shifting speed has been increased by 45% with the usual high shifting precision.

BT-DN300 internal battery
Integrated battery of the latest generation, which is recessed in the seat post or steerer tube. The internally routed cables give the road bike a tidy appearance. The integration of the battery into the frame also reduces the number of attachments that stand in the wind. The battery can remain in the bike for charging.

CS-R9200 cassette
The Shimano Hyper glide+ cassettes have set new standards in off-road use with their smooth upshifting and downshifting across the entire gear range. For the Dura-Ace 9200 group set, the Japanese have also adopted this technology for road bike use. You can now shift gears without hesitation, even when exerting maximum effort on climbs or sprinting to the finish line. This is made possible, among other things, by longer teeth. Despite the new design and the additional 12th sprocket, the CS-R9200 cassettes are compatible with previous 11-speed Road freehub bodies. Thanks to the use of titanium sprockets in the smaller gears, Shimano has succeeded in keeping the weight of the cassettes at the extremely low level of the previous 11-speed versions.

Dura Ace | XTR chain CN-M9100 12-speed
The CN-M9100 is characterized by its particularly smooth chain operation. This is not only noticeable when pedaling, but is also noticeable acoustically thanks to a 4db quieter drive. Thanks to a new chrome-plated surface in combination with the proven SIL-TEC coating, the service life of the chain has been kept at the same level as the M9000 chain, despite a smaller outer width.
