Hello how would you/one rebond a alu seat post shim into a carbon frame?

What is the best product?

Will it fail disastrously? Potential rider weight is 98kgs?

Frame is an on one race carbon frame.

Yours worriedly.........

2 part Epoxy (i.e Araldite) carefully and neatly prepared and done and left a good while to properly cure. Shouldn't be any danger of catastrophic failure in that location.

Epoxy, just get it from B&Q.

Wear gloves whilst doing it (infact wear 2 pairs, you'll stick your fingers together and pull them apart at least once!), and do it outside, it's very easy to become sensitised to epoxy then you'll be alergic to it for life. If you do get it on your skin, acetone nail polish remover will disolve it as long as it's still liquid.

Don't use 5 min Araldite, that's for household repairs not repairing composites.

3M DP-460 when I last looked into this a few years back, and indeed the repair held till I wrote off the bike in a massive stack at ft bill (and the repair held, the alu part cracked)

I dont normally post on here but seeing stuff that is way off the mark gets my goat...

The chances of becoming sensitised from one use of an adhesive epoxy to re-bond a seatpost shim back into a carbon frame are almost zero! As long as you dont eat the stuff you'll be fine indoors and without gloves.

If you do get it on your skin simply wash it off with soap and water. Using acetone is the worst possible thing to do, it dilutes the epoxy and all the nasty stuff is absorbed much easier into the skin.

Got to love the internet for miss leading information!
