Can anyone recommend a product to bond carbon fibre tubes into aluminium lugs as part of repairing a bicycle frame of the same construction- so i would assume a structural adhesive is needed. Obviously high strength is needed, and presumably a very small amount of flex? maybe one of the permabonds (et515?)- not sure which one? I am also concerned about corrosion of the aluminium- is this a necessary worry, and are there any mitigations?
