The Shimano Ultegra Di2 R8050 2x11 groupset with direct mount rim brakes


The Shimano Ultegra R8050 Di2 2x11 Direct Mount groupset is an electronic drivetrain groupset with a special rim brake set where the front brake is mounted directly on the fork and the rear brake directly on the seatstays. This provides more wind cutting power for the bike. The remaining components are assembled as with other Road bike groupsets: a crank with two chainrings (36-52 t), an 11-speed cassette (11-25, 11-28 or 11-30 t), a Quick-Link chain, Di2 shift/brake lever pair (STI), a Di2 front derailleur and a Di2 rear derailleur, as well as battery, charger, junction A (internal or external) and junction B. With the R8050 Shimano has introduced an Ultegra Di2 groupset, which is tuned to the needs of the rider according to the motto " rider tuned" .

- for internal junction box (EW-RS910), handlebar mount: 5 x EW-SD50 power cables (1 x for STI, 1 x for SM-JC41 = Junction B, 1 x for front derailleur = FD, 1 x for rear derailleur = RD, 1 x for battery) + 1 x EW-JC130 Y-cable junction box (connection between EW-RS910 = Junction A with STI and SM-JC41 junction box) + 1 x EW-JC200 junction box (connection between EW-JC130 and EW-SD50 to SM-JC41 junction box)**
- for internal junction box (EW-RS910), frame mount: 5 x EW-SD50 power cables (1 x to EW-RS910 = junction A, 1 x to SM-JC41 = junction B, 1 x to front derailleur = FD, 1 x to rear derailleur = RD, 1 x to battery) + 1 x EW-JC130 Y-cable junction box (connection between EW-RS910 and STI) + 1 x EW-JC200 junction box (connection between EW-JC130 and EW-SD50 to EW-RS910)***
- rubber grommets for internal cable routing
- wireless unit (optional): the wireless unit EW-WU101 allows you to display gear choice, battery status etc. on compatible bicycle computers or information displays. (When using a wireless unit, the EW-JC200 internal junction box is not needed).

* For the correct cable length ,the following frame measurements are needed:
- Length of down tube = distance between bottom bracket and stem
- Distance between bottom bracket and front derailleur
- Distance between battery and bottom bracket
- Distance between rear derailleur and bottom bracket
- Distance between shifters (STI) and stem centre

** For the correct cable length the following frame measurements are needed:
- Length of down tube = distance between bottom bracket and wireless unit or EW-JC200
- Distance between bottom bracket and front derailleur
- Distance between battery and bottom bracket
- Distance between rear derailleur and bottom bracket
- Distance between bar end and the next shifter (STI)
For Y-cable: 1. distance between stem and bar end with EW-RS910, 2. distance between stem and bar end and STI on the side without EW-RS910 (3. = distance between stem and wireless unit / EW-JC200 is determined, compare this to the cable length of EW-JC130 Y-cable junction box)
