Shimano 105 Di2 2x12 Disc Road Bike Groupset R7150/R7170 - 172.5mm

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

The R7150 is the first 105 groupset with electronic shifting. Shimano has also expanded its “Science of Speed” to the series, which is cheaper than Dura-Ace and Ultegra, and is equipping it with the completely renewed, semi-cordless Di2 platform. This works without cables at the crucial point, namely the interaction between the 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 switching speed to a new level - while maintaining high precision. But that's not all: This 105 group is also the first with twelve gears at the rear, so you have a wider range of gears at your disposal and are optimally prepared for any terrain. Practically, the 105 12-speed cassettes are also compatible with older Shimano Road freewheels. In combination with the advanced disc brake system, the R7150 lets you experience every day on the road bike in a new way and discover the road as a space of endless possibilities.

The 105 Di2 R7150 Road complete groupset from Shimano consists of a 2x12-speed crank with 34-50 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.
