Regarding which is real / which is fake, let me spell it out. A real dogma will have the following characteristics:
- External cable guides (apart from a small number of special edition Di2 only bikes)
- Large chunky rounded plastic cable guide under the bb. May be pinkish red or black
- Pinarello bar code above the cable guide
- 4 rivets holding braze on FD holder
- Carbon dropouts
- Aero shaped seat post
- Pinarello branded seat post collar and headset cap
- 60.1 paint design with Dogma 60.1 written on it throughout, and precisely positioned paint darts
- 99% of bikes will have standard colours, a few may have custom "My way" colours, but even these will use the 60.1 Dogma paint scheme.
- Some of the paint schemes use a distinctive diamond sparkle paint. Fakes don't have the same sparkle
- Pinarello brand on the down tube is positioned 2/3 of the way up the down tube with a twist so that the writing almost meets on the top of the downtube where downtube shift levers would be
- Very fine carbon weave visible on most paint schemes
- Asymmetric frame, with more ribs on the drive side of the down tube etc.
- Standard road fork (no tail) with tapering shaft and 1.25" lower bearing with standard deep groove bearing
- Italian bb thread
As above but:
- Internal cable guides with cable guide inset into a pocket in the frame, or Di2 holes and a cover for the cable guide pocket
- 60.2 paint scheme and Dogma 60.2 written on it throughout
- Still asymmetric frame, but with fewer ribs
- Fork with a distinctive "tail" keyed into the frame for aerodynamics and 1.5" lower bearing with standard deep groove bearing
As 60.2 but
- Cable port covers allowing Di2 or mechanical groupsets
- Optional lump of metal to hang Campag battery case from the bottom bracket
- 60.5 paint scheme and Dogma 60.5 Think 2 written on it throughout
- Fork with a distinctive "tail" keyed into the frame for aerodynamics and 1.5" lower bearing with angular contact bearing
- Still an Italian bb thread - press fit was only on photo models
To spot a fake you're looking for is consistency across the elements, with all elements above present. The first generation of fake Dogma 60.1 fakes had round seat posts, so were easy to spot. Now the fakers have added aero seat posts and a few have developed a bad copy of the "tail" on the Dogma 2's fork, meaning you do need to look a bit harder to get things right.
If you look at the "Prince of Spain" bike earlier in the thread you can spot it's a fake from a mile off as it has an aero seat post suggesting Dogma, but writing on the seat tube (and the paint job) says Prince. A bit more subtly the layout of the white darts on the fork isn't quite right, but the Pinarello down tube logo is pretty good. Then with better pictures you would probably see that the frame is symmetrical, uses two rivets not 4 for the FD, incorrect cable guide, barcode if it exists uses wrong font, 30K weave carbon....
If you wanted to make a convincing fraud, the easiest DIY way would be to get a fake frame with external cable routing or Di2 holes and get it painted in a Dogma 60.1 custom colour scheme which doesn't use the sparkle paint and completely covers the frame. Then add a real headset cap, cable guide and seat clamp from ebay. Only giveaways then would be the 4-rivet FD hanger, lack of asymmetry, the fork bearing design and lack of barcodes.
Very handy info, I didnt know the name for the darts, but yes ur right. The chainstay darts dont line up on it either, I had noticed.
