New Dropouts on this beauty
Hi, this is my sisters colnago. Her right dropout (derailleur side) broke off as she was riding it. Is it possible to fix this, and what would it cost? Pictures inside..

if you have the other piece, it can be welded back on. Otherwise there may be some problem getting a matching dropout. The photo isn't quite clear enough for me to identify it. In that case, both can be replaced with matching dropouts

Thanks! I'm afraid she lost the other piece during the crash...
So my best (if a bit expensive) option would be to buy matching dropouts and get a builder to weld them on. How much would a job like that cost?
Anyway thanks already!

Was it a fixed gear? I would have thought that the dropout would still be attached to the derailleur.
Are there any framebuilders left in the Netherlands? A person that does general purpose welding probably isn't going to do a good job. I might see if Colnago would fix it. Now that I stared at your pictures a little more, it's not likely that you will find matching dropouts, those are socketed.

Thank you for all the great advice, i'll put up some sharper pics tommorow. Any indication as to the price of a repair like this?
There are still a few decent builders left, but i'll have to contact them first if they're willing to do this kind of thing.
I would love to see this frame rideable again, as it was my sisters first bike and she is now a serious racer.
Thanks again, and good to know that this repair isnt impossible!

Sorry for the phone camera photo's :$
So the dropout is broken where the adjuster is placed, is this a weak spot usually?
But the fact that its socketed makes it a lot harder I suppose, socketed basically means that it fits over the tubes instead of going in, which means that I'll need specific colnago dropouts.
Any solutions?
I was thinking maybe replace the U shaped part of the dropouts, leave the rest on, like this:

the reason I mentioned that they are socketed is just because if they weren't there are lots of replacements.
repechage suggested grafting two dropouts together, that might work

Assuming there aren't any replacements, or Colnogo won't let them go etc... Could one not just cut the drops off then slot right throught the socketts. That is essentially the way some of these are done anyway. Sometimes folks who don't want to pour a lot of braze into an end will build and braze a bullet etc... Then slot it.
Another option would be these guys lots of flexibility and maybe they would be long enough to allow some fititng at the tube ends:

There are several angles to choose from.

Try CeeWay on the web. Drop outs inside and outside socketed and most everything
else for frames.

Thanks for all the great advice so far, I've contacted ceeway and asked them what I should measure to determine which dropouts I need (basically just the angle of the fork).
What I'm going to do is heat the dropouts and the sockets so the brass goes soft again, and then if all goes well just pull out the dropouts and put in new ones.
I'll put up pictures soon so you can see the progress!
@ftwekler: thanks, that would be a great help!

Yeah, will do. So in steps the repair should go like this (correct wrongs):
1. Remove paint from welding surface (to about 1'' from where the dropouts slot)
2. Cut dropouts in half.
3. Heat up (how hot should it be?) dropout and tube.
4. Remove both dropouts.
And then?
Does a welder pour in brass?
Also, I'll buy the dropouts from ceeway most likely, so first I need to measure the chainstay/seatstay angle.

have you tried vittorio cycles yet in Heerhugowaard? I guess you live in Amsterdam, so that's quite close. They have a big shop for all kinds of framebuilding repairs. Mario Verhoeven @ defietsenmaker.nl also sells dropouts, so maybe he can match yours if you send a pic of the broken one (he's a very friendly man to deal with btw).

Frankly, I think you will find that the investment to do it right is about the same investment it would take to have someone else do it for you - and I suspect that doing it yourself based on advice from the internet is liable to end badly for you. Good luck...
