I’m installing a Shimano R7000 GS rear derailleur on my bike to work with a 34t cassette for a trip to the Alps.
I’m finding the Shimano dealer manual ambiguous in respect of installing the ot-rs900 cable.
There are two plastic end caps, one with a tongue, and an aluminium end. What goes where, aluminium into the derailleur, and tongue into the frame?
Thanks in advance.
