(Language barrier warning! Please edit if I used wrong english terms)
After few years my generic rear derailleur started to fall apart, so I got new shiny one aaaand I have no idea how to mount that thing. Video tutorial authors seems to consider this an obvious task, with which I have some problems as my hardware seems to lack that hook thing to which you mount those hellish spiny devices with french sounding name that eludes my browser thesaurus.
I have no idea how half of those parts are called in my language, let alone in english, so I made pictures! Also, I never replaced this part, treat me as newbie.
And here is old and new: Old one was Shimano Tourney that came with bike, new one is Shimano Acera. Gearing is 7x3. (In my region choice is between no-name trash, pro-parts with pro-price and variety of Shimano, so I am pretty much stuck with this brand)
As it stands now when I just attach new one directly to frame, which is quite bothersome when its all coiled up, it can freely rotate around mounting screw (seems like feature) but nothing blocks it from going up (and screwing itself into cassette, which seems bad).
- Can i just mount it and proceed with servicing?
- Do I need some kind of adapter?
- Or maybe it is not compatible?
- How do you call that sideways regulation screw (with blue paint) near attachment point?
- Should this contraption go up on its? Is its position regulated by chain tension?
(Yes, I am replacing all cables as well) (Yes, I still have some cleaning to do)
