Does this 105 RD look misaligned or bent? The picture isn't great but the cage is 'leaning' in slightly and the the top jockey wheel is not vertically aligned with the sprocket it's running on. Or is this normal?

    looks more like jockey wheel issue/wear.

    Agree - the top jockey wheel looks well worn & leaning over in the cage.
    Probably time for a strip & clean & replace jockey wheels.

    To be honest I think the top jockey wheel is leaning a lot because the cage wasnt indexed correctly. It was too far to the right. Have adjusted it back but the cage still seems to leaning in a bit. Do all RD top jockey wheels have a bit of side play in them? Any reason why the cage leans in and isnt straight up/down?

    Better if mech was aligned with smallest sprocket for photo and agree that indexing looks out. All top pulleys 'float' ie move side to side.
    Make mine an Italian, with Campagnolo on the side..

    yes they float but the do not sit at an angle like that.

    the below pic is of the RD when indexed. It's looks like the entire hanger is naturally leaning away from the wheel slightly - which might be the reason the top jockey wheel is being tilted. The hanger looks a little better i press it with my finger towards the wheel, but then moves back after. I had the same issue with a 2300 RD and just ignored it. Don't expect it from a 105 RD as all 105's I have had, have been perfect.

    as requested a photo in the small cog. and that photo being at an angle does not help really but i am tempted to say hanger might be off but agian hard to say with it not being in the small cog.

    Ah right, OK, missed that sorry. Will get a photo in small cog a bit later (with small or large chainring?). If hanger is off then is this potentially an easy fix or new RD?

    Here's a picture of the RD on the smallest sprocket, both on the big and small chainring

    Seems to be a number of issues as others have said, knackered jockey wheels, alignment of the rear mech and looking at the photo a twisted mech, can't see whether the hanger is out, but any good LBS would have an alignment tool to check it out.

    So before I go any further, it's best to get the alignment checked at my LBS?

    How does it shift [on the road]?

    Shifts OK, not great. quite bad between gears 12-15. Drive chain (when in the big chain ring) sounds very rough in gears 17-25 (not that I use the higher end of that combo)

    Yep, at least then you can make sure that it isn't causing an issue.
