The new low-profile design of Shimano Shadow RD increases its shift stability and gives the rear derailleur a sleek and integrated appearance. Race endurance is guaranteed, through the optimized slant angle. The wide compatibility of two specific rear derailleurs (SS for cassettes 11-25T to 11-30T and GS 11-28T to 11-34T) will secure a smooth ride in even the highest and steepest mountain areas.

Shimano Ultegra R8050 Di2 Rear Derailleur is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by Topgun from Great Di2 Mech This is a very good rear mech. Upgraded from Ultegra 6870 rear mech. Very easy to install and set up, connected to etube app and updates rear mech firmware with no issues. Very crisp shifting and give me the opportunity to fit a 30T cassette if needed. This R8050 rear mech works with all other 6870 components.

r785 sti and r8050 mechs

is the new ultegra r8050 front and rear mechs compatible with r785 road disc brake sti levers. i have a road frame which has post mount calliper mounts front and rear, i wanted to buy the new dura ace r9120 groupset but shimanos new road disc callipers are all flat mount, i am told that there is no adapter to solve this issue, also i thought i could use existing rs785 callipers with new ultegra di2 disc sti levers and then i learned that the newer sti levers use bh 90 hoses and the older callipers use bh59 , are there any adjustments i can make. can i at least use r785 sti levers with new r8050 mechs
Asked by: paddy001
I can advise that provided your shifters are di2 then this should be suitable, please note you will need to reprogramme your di2 if you make any changes.
