  • I have reglued three carbon / alloy frames, one over 10 years ago, with araldite, and they are all still in use. The critical thing is to prepare the surfaces to get a good bond, first remove anything loose, like bits of old glue, and then clean the whole lot with lighter fluid. Leave it to evaporate, then apply the glue. Be very very careful with the mix, you have to get the ratio of adhesive to hardener exactly right.

    The beauty of triangulation is that the forces through the frame are well dispersed, so once the glue has set (leave it at least 48 hours to allow full curing) the joints won't be under too much load.

    The BB area fails due to water especially salty water getting in to the joint. This is also true of the lower joint on the head tube. Before you do any gluing wrap some old inner tubes around the down tube and see if there is any sign of the joint at the top being loose, because if it is it will be quite a pain to redo it once you have glued the other two frame tubes, so now is the time to find out.
