Shimano Ultegra 12 Speed Disc Brake Di2 Groupset From £1199.99

Shimano's latest Ultegra 12 Speed disc brake groupset gives their fastest ever shifting with wireless controls.
The new 12 speed cassettes will fit any 11 speed Shimano pattern freehub so no need to change your wheels.
The semi-wireless system, which does away with wiring from the shifters to the derailleurs, means a much cleaner build on bikes.
Shimano has also retained its long-life, large-capacity seatpost/tube-mounted battery, which is wired to the front and rear derailleurs.
Shimano have integrated the charge port into the rear derailleur, meaning you no longer need a separate junction box mounted under the stem, at the end of the bar, or integrated into the frame.
The internal BT-DN300 battery provide up to 1,000km between charges.
Both Ultegra R8100 and Dura-Ace R9200 bring full, built-in Bluetooth connectivity to Shimano’s electronic groupsets without needing any additional parts. That means you can pair the groupset to a compatible bike computer and have easy access to the system’s gear shifting options through Shimano’s app.
NB - The group can be customised by selecting your desired components below. If you do not require a bottom bracket or disc rotors then those items can be left out.
