Shimano 105 Di2 complete group, 12-speed - 50-34 teeth

SHIMANO 105 Di2 DUAL-CONTROL LEVER
The new SHIMANO 105 shift/brake lever enables electronic Di2 shifting for the first time, allowing even more riders to switch gears precisely and intuitively. With reach adjustment and individually customizable button functions, optimal ergonomics can be found.

SHIMANO 105 BRAKE CALIPER
With proven hydraulic braking technology, the new SHIMANO 105 brake calipers impress with the SHIMANO flat-mount system and their optimally flat profile for racing bikes. More compact and lighter than ever before, the R7170 brakes offer a wide brake pad clearance, allowing for easy wheel removal, quiet performance, and easy, thorough maintenance thanks to one-way bleeding.

SHIMANO 105 Di2 FRONT DERAILLEUR
The electronic shifting operations of the SHIMANO Di2 system make it easier to shift from the large to the small chainring and vice versa, reducing the risk of chain drop. Additionally, shifting at the rear no longer requires trimming the front derailleur to prevent chain rub. In the E-TUBE app, fully and semi-synchronized shifting functions can be selected. Thanks to the digital precision of the electronic shifting and its coordinated communication between the front derailleur and rear derailleur, the SHIMANO 105 front derailleur offers an excellent shifting experience.

SHIMANO 105 Di2 REAR DERAILLEUR
Versatile, 36T-compatible 12-speed Di2 rear derailleur. Triggered by the wireless shift signal from the shift lever, the extremely powerful motor of the SHIMANO 105 rear derailleur performs a shift operation within a fraction of a second in conjunction with the optimized link structure. The rear derailleur is the heart of the Di2 system and combines charging port, LED indicators, adjustment switch, and more in a compact package. The flat profile reduces the risk of damage from contact and falls.

SHIMANO 105 CRANKSET
The newly developed cranks offer a perfect balance between efficiency and low weight. Made of aluminum, the crank is black anodized and offers an attractive and luxurious appearance. The plastic ribs on the back of the chainrings represent the unique structural design of the SHIMANO 105, allowing significant weight savings with crisp shifting performance.

HYPERGLIDE+ CHAIN
The M7100 chain offers better chain retention thanks to enlarged inner links. The new chain features a quick-link chain lock and a SIL-TEC coating for longer life under off-road conditions.

SHIMANO 105 HG CASSETTE
The 11-34T cassette is suitable for sprints on flat terrain as well as steep climbs. It is compatible with both 11-speed and 12-speed FREEHUB bodies from SHIMANO.

CENTER LOCK BRAKE DISC ICE TECHNOLOGIES
SM-RT70 brake discs ensure powerful and consistent braking performance under all conditions. The ICE TECHNOLOGIES brake disc ensures significantly reduced heat development in the braking system. This guarantees consistently high braking performance even on steep descents. With the SHIMANO CENTER LOCK mounting system, the brake discs can be quickly and easily mounted thanks to the lock ring design.
