I’ve 2/3 bikes which I’d like to add derailleur hangers to, they were never designed with derailleurs in mind.
One is a Charge Cooker Single speed, and I have 2 Charge Mixers (having recently adopted a second)
I’ve so far ridden the mixer with a filed and butchered hanger made to fit. Just using the QR to clamp it in place. Worked well, but looking for a more permanent and cleaner solution.
Any recommendations for a more robust solution much appreciated. It’s doesn’t need to be a DIY job, in fact, unless there is a suitable hanger ready to go, I’d rather a professional made a decent job of it.
In South East London should anyone know of someone with the right skill set. I did find someone but completely lost contact.
this would be a reasonably straightforward job for someone with welding skills. While they are at it, they could probably fix those dreadful flimsy-looking mudguard eyes, too.
A snag is that those dropouts are cast and they are not thick-walled. They sometimes break all by themselves anyway, and adding a gear hanger in the usual place, without suitable reinforcement, will risk breaking the dropout the first time the bike falls over.
A framebuilder would probably suggest replacing the dropouts as a favoured option, although this isn't perfectly straightforward because of the height of the current ones. He'd also most likely suggest additional braze-ons for the cable runs too, if they are necessary.
Its not clear what you are trying to do here exactly but in general it is a better idea to buy a suitable frame than it is to start messing about, unless you are equipped to do the messing about; by the time you have paid for the work and the required respray, you are up to the same cost as a replacement (used?) frame? Currently the frames you have are readily saleable, but after they have been modified, maybe not.
Taylor-wheels.com have nexus 8 wheel sets available again for c€165, I don't know if they can ship to the UK at the mo but a quick look didn't indicate they couldn't.
Hamster - I have a temporary solution, I eyeballed the closest hanger I could find, and took a hacksaw/file to it. Its clamped on via the Hex Skewer and seems to work. but it’s not attached, just clamped, as I’m not making the holes in the dropout.
Greystoke - thanks, but not looking for another IGH, I have a Alfine 8 which I can't get to work, and an 'working' Alfine 11 which the disc brake part of the shell has failed on. Next summer when I can sit in the warm garden, I may try and fix the 8, and the 11 I’ll keep a look out for a new shell. But I don't have a need for them unless my commute changes again and don't particularly enjoy riding them for leisure.
Brucey - I appreciate that its not the most economically sensible, but you like what you like, and I really really like these bikes. Geometry and feel, (steel, plus they have EBB which is my preference for disc single speed) . I've had a few others frames but have come back to these , the Mixer I’ve built up as predominately Single speed, but have chucked a 10 speed on the back and taken it on a few longer rides and prefer it to my road bike. The cooker I’ve tested with a 10 speed on the back for some trails and in both modes (SS and 1 x 10) it has been very enjoyable.
That picture is not my actual bike, if I had uploaded I’m pretty sure the thread would have derailed into chain maintenance, how to correctly paint a bike (not the way I’ve done it), and generally cleanliness/upkeep, so those mudguard eyelets are redundant for now, and unless needs change will probably stay that way. Getting a cable boss for a possible FD would be useful, rear too, although I run full outers to the rear and don't have any issues with it.
Your comment on the strength of the dropouts concerns me a bit, these bikes do get thrashed a bit, if adding a hanger is likely to weaken it maybe I’ll rethink it. and stick with my current bodge.
https://gearmechhanger.com/epages/95001 ... Categories used to do custom hangers. I don't know if they still do, but they have a catalogue of 'CNC' hangers, so I would presume it's possible. If not, maybe they can put you onto someone who does.
Otherwise, a variant on the universal or 'emergency' skewer mentioned above could maybe be customised for your bike? Or you could make a better version of your bodge (which honestly looks ok).

How about using that hanger but chemical metal epoxy to secure it to the other side of the cast lug?? Seems like there is plenty of material to secure.
Shimano do a fairly low end rear Mech that has an eye that fits over the end of the axle , integral to the Mech, rather than bolting to a D plate that sits in the long dropout that you don't have, or screwing into the integral Hanger you don't have either. Cheap Mountain Bike Fare I am afraid, and not sure of the model (got one in my spares box I think)
The outer diameter might be too big to sit inside the edge of the raised radius around the edge of you fork end though.
Just been on e Bay, Shimano Tourney, there's a used one that illustrates how it fits . I got it slightly wrong, it is intended to screw into an integral Hanger Looking at the picture reminded me. But rather than having a tube with along Allen bolt, it has a flat plate with a short Allen bolt. Got to be worth trying it direct on the spindle without the Allen bolt.
Shimano do a gear cable stop that clamps round the Chainstay. They also do cable guides that clamp on the seat tube or down tube in lieu of braze on stops. Might not fit if your frame has oversize tubes. You can also get a plastic cable guide that sits under the bracket .

Unless I have missed something, derailleur mounted on the Chainstay died out in the thirties or forties. Google Cyclo Gear . Fitted on a plate bolted round the stay on two slots , sometimes the plate was brazed in place.

Nope alive and well in this century, the arrangement is used on some folders and i have seen it on several utility bikes too.
Convention? what's that then? Airnimal Chameleon touring, Orbit Pro hack, Orbit Photon audax, Focus Mares AX tour, Peugeot Carbon sportive, Owen Blower vintage race - all running Tulio's finest!
