Description

To get cyclists and mechanics started with the updated and redesigned Di2 shifting system for Ultegra R7100-series 12-speed components, Excel Sports is offering this special component kit package for faster, easier purchase. You get the key Di2-related components and essentials that are required for a 105 Di2 frame build with hydraulic disc braking. We have also included the new Battery, a 12-Speed chain, and the 11-34T R7100 cassette. Other components that have options specific to a frame/rider/set-up are offered separately..

The 12-Speed R7100 series is only available in the new Di2 system, and won't be offered for mechanical shifting. Shimano is referring to this as "wired-less", as the shift levers powered by coin cell style batteries, while an internal seatpost mounted battery is wired to the front and rear derailleurs. This eliminates complicated E-Tube wire routing in today's fully integrated cockpit and keeps the system in premium efficiency all around. The engineers believe in the value of a long running battery and the proper power to drive the servo motors of the derailleurs. Every detail, every decision, and every component of the R7100 series is engineered to deliver a faster, more reliable, and more intuitive ride experience than the previous generation. Shimano dedicated years of research, development, and testing to re-imagine and improve this Di2 system, and now have brought it down to the 105 level.
