Description

The new SHIMANO 105 brings Di2 shifting to a new set of riders. For those who have only experienced mechanical shifting and ergonomics, SHIMANO 105 Di2 represents a transformation of the road cycling experience.

With function and technologies inherited from DURA-ACE and ULTEGRA, SHIMANO 105 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, SHIMANO 105-optimized gear combinations, and an exceptional brake system, the new SHIMANO 105 marks a new era of affordable performance.

Description

The R7150 is the first 105 groupset with electronic shifting. Shimano has also extended its ” Science of Speed” to the more affordable series compared to Dura-Ace and Ultegra and equips it with the retreaded, semi-wireless Di2 platform. This works without cables at the crucial point, namely in the interaction between STIs and 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 raises the shifting speed to a new level – with consistently high precision. That’s not all: this 105 groupset is also the first with 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. Combined with the advanced disc brake system, the R7150 lets you experience every day on a road bike anew and discover the street as a space of endless possibilities.

The 105 Di2 R7150 Road groupset by Shimano consists of a 2×12-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 rechargeable battery, a Quick-Link chain and a cassette with 11-34 or 11-36 teeth are also included.
