This "Art Decor" design codename THDK for V2-R (CHDK/ CHDB for the Colnago Concept), is based on the "Arabesque" art form - basically, repetitive rhythmic patterns of scrolling and interlacing natural elements such as foliage and stems. The Arabesque style was found in early Islamic art since the 9th Century and also in European art since the Renaissance period. Therefore there is a strong historical link between this art style and Italy. Having the Arabesque style on an Italian brand like Colnago is therefore not surprising.
Colnago first introduced this Arabesque style into the lugs of their "Arabesque" steel frames produced in the 80's (see photo), which are now very popular among Colnago collectors - I think more so because they were produced in smaller numbers compared to the more popular Master steel model then.
The Arabesque steel frame was recently reintroduced in very limited numbers (story goes that an employee found some unused original arabesque style lugs and the rest, as they say, is history). I guess that probably inspired Ernesto himself to personally design the Arabesque motifs onto the paintwork of the new Concept frame in limited numbers as code CHDK/CHDB and now also on the V2-R as THDK (I don't know if Ernesto himself did this artwork again or will it also be in limited runs).
I think that the infusion of this older art style into the modern bicycle, especially top of the line road racing speedsters is bound to create polarity in views.
I myself am a traditionalist but I appreciate and enjoy technological advancements. So to me, this fusion of old world form with new world function is perfect. The Arabesque form was still popular up to the 60s and 70s (my era), but I can see how younger generations may not appreciate nor even recognise it. I also feel that not many mainstream and newer brands can pull off this fusion of old and new worlds as they lack the heritage to do so. This makes the CHDK/CHDB and THDK all the more special - just my humble opinion.
