I'd spotted that already
so main triangle is titanium and rear and fork are Reynolds 531? What's it feel like to ride?
Is this a shim or meant to be there?

DynaTechs came in lots of different tube sets, the DynaLite tourer was 2055 tube set, pretty low down the scale, good reading here:-

All use Reynolds tubing but I think the usual designations, 531, 753 etc are a bit spurious when applied to DynaTechs as they refer to definite tube-set specifications; butting, wall thickness etc, not just the metallurgy. Maybe that’s why Raleigh avoided mentioning much about equivalence (although they did once in a German Catalogue).
When my DynaTech Pro got wrecked after being run over, I decided to cut up some of the tubes to see how it was made… there didn’t seem to be any conventional butting as such, it was pretty much plain-gauge. IIRC the down tube was slightly thicker at one end, but there was no step just a gradual taper. Presumably the bonding process negates the need for thick butts as there’s no welding involved.
