Shimano 105 Di2 2x12 Disc Road Bike Group R7150/R7170 - 172.5mm - from Neurad

Shimano 105 Di2 2x12 Disc Road Bike Group R7150/R7170

The R7150 is the first 105 group with electronic shifting. Shimano has also extended its "Science of Speed" to the series, which is cheaper than Dura-Ace and Ultegra, and has equipped it with the completely redesigned, semi-wireless Di2 platform. This works without cables in the crucial area, namely the interaction between STIs and the rear derailleur. Cables are only used between the battery and the rear derailleur or front derailleur. The wireless protocol is extremely fast and reliable, which takes the shifting speed to a new level - while maintaining the same high level of precision. But that's not all: This 105 group is also the first with twelve shifting levels at the rear, so you have a wider range of gears available and are optimally prepared for any terrain. Conveniently, the 105 12-speed cassettes are also compatible with older Shimano road freewheels. Combined with the advanced disc brake system, the R7150 lets you experience every day on your racing bike in a new way and discover the road as a space of endless possibilities.

The 105 Di2 R7150 Road complete group from Shimano consists of a 2x12-speed crank with 35-52 tooth gradation, a flat-mount disc brake set and an electronic rear derailleur and front derailleur for semi-wireless shifting. Of course, a battery, a quick-link chain and a cassette with 11-34 teeth are also included.
