It is a 20 year old frame, carbon fiber tubes with aluminium lugs. The tube has come unbonded from the lug.
Can a repair be done?

    I have an old Look KG96 in need of repair. The rear drive side alloy dropout has become unbonded from the carbon rear triangle (on the chain stay). The frame is intact and undamaged it seems to just be a case of coming unstuck. I would like to know how to rebond together again, is there a particular type of epoxy anyone can recommend for alloy to carbon bonding? I can't afford a professional job :(

    Karlos69, how did you get on?

    Aluminium lugged frames unglueing is due to galvanic corrosion - they can be repaired but you need to clean-off any white corrosion deposits from the alumnium and then put some sort of barrier coating on the metal before re-bonding. Suggest you look at the Devcon range of adhesives rather than something like Araldite which is fairly brittle. Would also suggest you need to jig-up the frame to keep everything aligned whilst the glue cures.

    The guys at Carbon Cycle Repairs are going to have a look at it when I am next in the area (Peak District)

    Meanwhile I have bought a Giant TCR Composite 1 to be going on with...
