Shimano Ultegra 6870 Di2 Groupset
The highest quality groupset outside of the professional peloton, Shimano’s Ultegra 6870 Di2 Groupset offers crisp, accurate, and reliable shifting at a fantastically light weight. This Shimano Di2 option will be an excellent addition to the aspiring racer or to the rider who just enjoys optimal performance.
Concentrate on Performance
This Ultegra 6870 Di2 series features “pro proven” electronic shifting, a direct trickle down from its big brother, Dura-Ace. Featuring 4-arm cranks, an 11-speed cassette, dual pivot brakes and a Sil-tec chain, this Shimano Di2 groupset uses an electronic shifting system to let you reap the benefits of supreme shifting so you can keep your concentration where it’s needed – on the road ahead.
Ultegra E-tube Platform
The Ultegra 6870 products are based on the E-tube platform. They can be adjusted with the dedicated E-tube (project) software. E-tube is Shimano’s electronic shifting program that lets you customise shifting functions. Besides customisation, E-tube offers the possibility to upgrade components with firmware upgrades after the point of purchase. With E-tube compatibility you can include other shifting functions like Roubaix shifters or Dura-Ace sprint.
