My Derailleur Hanger broke and I want to replace it. However, I couldn't find any information about my bike or model or what kind of hanger I need to buy. The brand is Esperia and model name is Aria.

Here is the photo of the broken hanger:

I even tried calling the seller, they said they can't help me with that since they are just resellers.

So, I tried to check the bike to see if I can find anything helpful and I saw that speed gear was Shimano RD-2300. Is the hanger special to this Shimano model, If no how can I find the correct hanger for my bike?

    The hanger is specific to the bike frame. Tell us what bike frame you have, or post a picture of that. – John Zwinck May 27 '17 at 7:49

    A decent LBS will have a collection of RD hangers to chose from. – Carel May 27 '17 at 10:10

    If they don't stock it most shops have a wall chart with 200 or so "to scale" pictures they can match it to. – mikes May 27 '17 at 11:37

    Yeah. You can also look online at wheelsmfg.com/derailleur-hangers.html – Batman May 27 '17 at 13:59
  • @takobaba - I'd take it to a bike shop so they can match it to the chart they have. It's very easy to get a hanger that looks similar but isn't quite right unless you find it by the bike's model number. – Batman May 28 '17 at 14:22

Yours rotated looks like enter image description here

Best I could find is http://wheelsmfg.com/derailleur-hanger-6.html which is "similar" but the mount holes look too large, the duck bill is way wrong, and the curve is there but wrong.

The holes might kill it, but its possible the other parts aren't critical.

Don't bother with the emergency hangers for long term use - they don't last long and they don't work well.

  • Your option now is take it into a LBS and ask for "what's close enough" ? – Criggie May 28 '17 at 12:35

    @takobaba - If you did find the correct derailleur hanger, you should answer your own question (and accept) so that the thread can be closed. – Rider_X Jul 27 '17 at 18:21
