I have a carbon frame and the derailleur cable stop on the chain stay is slightly loose and if I tried, I could probably remove it.
Would it be correct to use a two part epoxy resin adhesive to hold it firmly in place or is there some other adhesive which would be more appropriate please ?
Does anyone have any recommendations please ?
Thank you.

As always pics would help. On some older carbon frames, cables stops and guides are riveted on. Clean up any corrosion that might be around the stop. I think epoxy would work fine for that scenario.

Not all epoxies are compatible with each other. eg: adhesive epoxy is different than polyester fiberglass epoxy (there are many more). I know nothing about carbon fiber repair so I can't help much there.
I recommend consulting someone who is familiar with carbon fiber resins to find an adhesive that won't pop off after 5 miles, or... if the manufacturer is still in business, try contacting them and get their recommendation.
One rule of thumb to keep in mind, when it comes to epoxy adhesives, the longer the resin takes to set, the stronger the bond.
Sorry about the ramble...

Polyester resin for fiberglass isn't an epoxy. Standard two part epoxies work pretty well on carbon fiber - longer cure times are better. Devcon 2 hour is a good one. Don't buy epoxy that is designed for use on plastics, that is chemically different.


But before you do anything else, figure out how it is supposed to be held together. When epoxy parts come apart it is usually all or nothing. It sounds like you have a loose rivet, which would be best drilled out and re-riveted.

Its C&V, probably someone has to ask.. is anything made in carbon fiber too new to be considered ...

Off the top of my head:
Graftek. Trimble. ALAN. Vitus. Peugeot. Aegis. Maybe early Kestrel. All before 1990

And if you count wood as a "carbon fiber," the Old Hickory.

Thank you for your thoughts. The frame in question is a Wilier Imperiale De Luxe, probably dating from the mid 2000 -2010 period, which appears to be oterwise in exceptional condition, with hardly a mark on it.
On a more general subject, I have read that carbon frames can break and this is a concern.
Some time ago, I bought an earlier Wilier Aluminium frame which came with a carbon seat post. The seat post was split halfway across it's width - how this had happened, I have no idea but it raises doubts in my mind, about the fragility / strength of carbon items.
"All is not gold that glitters" comes to mind !

I'm sure it's a nice bike, if not either classic or vintage, but I'm not the thread police.

Again, this might not be the subforum to bring that up in.
There's plenty of information out there about CFRP and its failure modes, most of which can be avoided by good engineering and reasonable care. C&V isn't really the place for that general a conversation about it.
