looks nice, how'd you like the frame? Those thin stays aid comfort? Only thing I would try and do ( if you're going all black) is get the rails on the saddle black , either sprayed or coated somehow. They just seem to clash with the all black. Or the obvious answer as it's WW get the carbon railed version antares! Derailleur cage black somehow too! Black bolts here and there? Just being hypercritical. Take no notice! Just jealous of a stealth build....maybe a NEGRA stealth logo?! EDIT.... I have re read, you said no logos, ignore me.
To be honest, I can't tell if the comfort comes from the stays or from the light spokes and very light rear wheel. About that real wheel, triple crossing in both sides of the wheel was not a perfect idea. I think radial lacing on the non-drive side and crossings on the drive side is a better choice, as right now the tension is too different. I want to change spokes on the non-drive side soon. Wheel will be stiffer, and a tiny bit lighter and will look cooler. Frame has superb finish, although right now i would have chosen the FM029, which is a bit lighter, has a more compact geometry, better sizing and internal cable routing.
I also want to change the bolts that hold together the butterflies of the playspeed pedals, i have to look for a place to get them. Also the bolts that hold the spindles can be switched to aluminium. Groupset will be eventually changed by something lighter, perhaps sram, but that's not gonna come soon. I have to first waste this groupset. Dura-ace cassette may come soon though. Alligator shift housing is not working perfectly yet. Right now i´m using low quality cables of 1.2mm. Maybe switching to sram 1.1mm cables will solve this issue easily.
Geometry is a bit too racy for me I think. I cutted the fork too low, I carry now too much weight on my hands, I may buy a new fork and cut it longer. Also waiting for specialized BG blue innersole. With these two things the fitting will be at 99% perfect.
