Out on the winter road bike today, shifting from wee ring to big ring and the cable stop comes clean off the frame!
Looks as though the bonding (however that was done) just came away, there's no damage to either the frame or the cable stop itself.
As its an alu frame rather than steel I guess welding is not the way to go, and I'm wondering if epoxy is the best bet. Then I came across this JB Weld stuff (which I'm hoping I can get at Halfords or B&Q or somewhere on the way home) - has anyone any experience of this?
Cheers!
If you make sure everything's spotlessly clean(no oxidisation either), and put a big enough fillet around it, then you may be lucky, but I doubt it. At one time, Tektro (and a couple of others)were making clamp on cable stops for V-brake fittings, you may be able to lay your hands on one, or even make something similar to do the job.
Sorry but I'm saying no ... it'll come off again pretty quickly.
Hmmm, kind of suspected that given that it must be under constant load.
Other than some kind of clamp-on bodge (which I reckon is also unlikely, given the downtube is an aero shape) is this pretty much curtains for the frame?
Try an old-fashioned roadie shop. In the 70's it was the fashion to have all the stops and guides taken off your frame and use screw-on chrome guides.
'is this pretty much curtains for the frame?'....What about a 'rivnut' set into the frame?

You will then need to fettle a cable stop with a threaded end. I have the tool if you want to give it a try.

I wouldn't rely on JB Weld, Milliput or any of the other similar epoxy resins for something like that.
Find someone local to you who can [b]TIG[/b] weld aluminium.
It is possible to [b]MIG[/b] weld aluminium, but it always looks a mess and isn't ideal on thin gauge frame tubes.

Marko - could you tell me a bit more about this? Not something I've come across before, cheers.
A rivnut is a rivet witha threaded hole down the middle. You drill a hole in your frame, screw the rivnut to the tool, insert and squeeze the tool. the Rivnut expands to grip in the hole.
You would need a steel cable stop brazed on to a shallow headed bolt or threaded bar. then screwed in the rivnut with some loctite so it can be fixed in the correct alignment.
Some manufactors fix bollte cage bolts to new frames with rivnuts.
or 1x10 and MTFU 😉
Another thought - would using a full length outer cable-tied to the downtube work as a bodge? Its the winter bike, so looks are not important!
