Shimano 105 Di2 R7150 50-34T 2x12 Hydraulic Disc Brake Bicycle Group Set

The R7150 is the first 105 groupset with electronic shifting. Shimano has also expanded its "Science of Speed" to include the more affordable series compared to Dura-Ace and Ultegra, and equipped it with a coated, semi-wireless Di2 platform. This works without wires at the most important point, namely the interaction between the STIs and the rear derailleur. Wires are only used between the battery and the rear derailleur or front derailleur. The wireless protocol is extremely fast and reliable, which continuously raises the gearshift speed to a new level with high precision. And that's not all: This 105 groupset is also the first to have twelve rear gears, so you have a wider gear selection and are optimally prepared for any terrain. Conveniently, the 105 12-speed cassettes are also compatible with older Shimano road freehubs.

Shimano's 105 Di2 R7150 Road groupset consists of a 2x12-speed crank with a 34-50 tooth grade, a flat-mount disc brake kit, and an electronic rear derailleur and front derailleur for semi-wireless shifting. Of course, a rechargeable battery, a Quick Link chain and an 11-34 tooth cassette are also included.

Features:

• * Internal battery mounting on the seat post, run time approx. 1000 km
• * Two CR1632 batteries in each STI for wireless shifting
• * Front derailleur connected to battery by cable
• * Rear derailleur with wireless chip, LED display, charging socket and function button, wired to battery
• * Cassette with wide gear range for all terrains
• * 10% more free space for brake pads reduces noise generation
