My comment was just a matter of fawning over the Somec engraving which in my opinion is beautiful (even though I hate when they pantograph right over the brand name). The Somec is engraved deeply and the red swirls are really cool. I would have preferred they did it around the Cinelli oval on the top however. And I am aware of the process of pantograph-ing, and the difference between that and engraving, which often is more "artistic".
I really LOVE that viking head chainring though. That is too cool. Was it a Viking product rebrand?
The Peugeot/Raleigh/Motobecane rebranded engraved cranks never did anything for me, but to each their own.
+1.
Yes, it is pantographing. And yes, it is art. Bad art, in my opinion, but that is beside the point.
A pantograph is simply a device for mechanically reproducing a design at a scale different from the original. It is in this case used to control a router to engrave designs on aluminum. You can engrave anything you want on anything you want, but you wouldn't do this to any material other than aluminum.
Proper OEM components, ordered from the supplier by the bike manufacturer, are another matter.
