• Are rivnuts a Tester approved™ method of adding bottle cages to a steel (Reynolds 520 or 531, so suitable porky I'd say?) frame. And if so, would you recommend something like Loctite or a Huntsman epoxy between the nut and the frame? And if not, what else?

  • if not, what?

    The proper method is brazing.

  • Adding glue does nothing to help the nutserts hold, if they are installed correctly.
    The image is showiing stainless steel nutserts into stainless steel.
    Bikes usually have aluminium ones as they are easier to set.
    I have nutserts, setting tool and a 7.1mm drill if you fancy doing it yourself? 7.1 mm is the size for M5 nutserts. (rivnuts is an americanism).
