hello.....i have had a bottle cage mount rust out on my nomad, i think the mounts are rivnuts, and are not welded/braised on , so its just the paint stopping water getting in between the rivnut and the steel.....The bottle cage mount had a 1.5 litre bottle cage , so heavier and i guess quite a bit of sideways stress/vibration as was the on the frame diagonal .The paint cracks , water in , rust.
Had it welded closed, and using a clamp-on cahe mount now

I am surprised it is a rivnut. Rivnuts work best on a flat surface and on a cycle frame tube the flange of the rivnut would stand away from the tube.

Nomad can mean many different bikes. The UK hand built frames, the Mk I and Mk II frames that were welded in Taiwan that are now out of production (I own a Mk II), and the current Nomad Mk III frames. All are very different from each other.
I think the bottle mounts on my Mk II are not rivnuts. The bottle cage mounts on my non-Thorn titanium bike are, thus I can see the difference.
On this forum years ago I recall reading of a Thorn (I think it was a Nomad Mk II?) that had a rust problem that was specific to the downtube S&S coupler.
