Apologies if this question has been asked before but my rear 105 5800 derailleur has given up the ghost, the thread on the inner plate is stripped,and i'm doing a coast to coast ride on Monday!! Its a GS (medium cage) and I can't find anywhere local (Chorley, Lancashire) that has one in stock, (or even the inner plate)
I thought that the latest r 7000 derailleur would work, but I've been told that this will not work with 5800 shifters?? This suprised me as I thought all 11 speed shimano was interchangeable.
Has anyone fitted a r 7000 mech with 5800 shifters? Are they compatible?
In addition, a long shot but does anyone in the North west have a 5800 medium cage mech for sale or even the inner plate off an old one?
Thanks in advance. Phil
