quite simple :
1- Québec is huge and has many rivers
2- government build dams to make hydroelectricity (sadly flooding many First Nations lands but that's another story)
3- aluminium companies got rebates over the electricity price (producing aluminium takes a lot of electrcity)
4- Alcan was born out of this and high quality aluminium was produced on the Côte-Nord (north coast of the St-Layrence River)
5- Da Vinci (originally) / Devinci (now) was born out of this industry's traces and invested a lot in the R&D for a small team
think of this frame as a quality on pair with Duralcan found on S-Works M2 made-in-usa with Alcan aluminium composite
tubes are generally non butted so they don't have dents and the weight is quite similar to titanium
the energy was invested in the quality more than the advertisement
I think that, in the long run, people will understand the value of these frames, like you seem to be doing.
the blue lettering looks nice over the scratched aluminium
the patina would shine with a new pair of tan wall rubbers...
