    Had a bit of a mechanical :(

    Happened on a straight, with little pressure on the derailleur.

    Is a new rear derailleur needed, or anyone know a magician who can fix something like that?

    New bike by the looks of that.

    Seriously it looks like you have destroyed the cage and the inner cage can be hard to source. Easier to get a new rd.

    I would guess a quite an old bike, possibly 70's 80's Reynolds 531 butted tubing.

    When was the last steel framed bike fitted with an non-replaceable derailleur hanger?

    Most important thing would be to check that the rear derailleur hanger hasn't been twisted, if so get it professionally straightened.

    If it breaks you will have to put up with a fixie. :p

    A new cheap RD would be cheaper than getting the parts or labour to fix it. get yourself a chain breaker (if it's not a powerlink connected chain) and DIY.

    At the angle the bolt going into the frame from the RD is at, I'd say that the hanger has had it. That said, it could just be the picture angle.

    It's a Surly Cross-Check, ye cheeky buggers.

    That's a 2007 (or possibly 2006) Ultegra 10 speed RD, I don't know what model number.

    I've had to bend a steel hanger before and it was fine. YMMV but you should be OK T. New derailleur is gonna run around the 50 -60 quid mark. As Hungrycol said again you source parts you'd likely be looking nearly the same amount, never mind the time and hassle.

    Still if you're not comfortable with a stilson and bending and aligning the dropout hanger maybe the local bike shop might be the better bet though. I'd give it a whirl but I would be a guntherer(and cheapskate). A misaligned derailleur hanger would turn you to drink trying to get the gears to shift right.

    Rejoice in the awareness of feeling stupid, for that’s how you end up learning new things. If you’re not aware you’re stupid, you probably are.

    I hate the expense, but I might just decide to get the LBS to sort it all out. I suspect I need a new cassette too. Last time I was in the poor guy nearly fell over when he measured my chain, so that's new but the cassette and RD are the originals - I reckon that could be the "why" of this one :)

    If you want to try straightening the hanger your self and happen to have a spare rear wheel axle lying around (10X1mm thread pitch but not all are)
    just thread it into the hanger and bend (GENTLY AND SLOWLY) it's very old school but does work, very hard to align it by eye though, nothing beats a stupidly expensive hanger alignment tool after all :D
