Is Epoxy Carbon Safe?

[JScycle]

Hey All,
My fender mount has pulled out of my carbon frame. Can I epoxy it back in place safely?

Where has it pulled out, what damage has it done to the underlying tube?

Hey. Attached are two photos. One is the mount pushed all the way in/normal the other photo is the mount pulled out as far as it will slip. Basically I can still use the fender it is just wobbly.

By the looks of that, I'd just run a bead of epoxy round the gap, and push the boss back into place. Leave to cure. Might need to strip stuff down a bit so you can get proper access. And hold it in place with some tape while it cures.

I was expecting some sort of great big ragged hole with torn CF everywhere!

If it's a rivnut you could drill it out and put a new one in.

This. I had a rivnut go on my Cervelo BB external cable guide. Bought a Rivnut tool and some Rivnuts for about £35 and it was pretty straight forward. I practiced on a bit of scrap metal first. Dont frig about with a home made rivnut tool made from a bolt as seen on You Tube though.
