Couple more shots:
Sheesh, that's a nice looking hub. Did you build the wheels or did you have them built up? This may be getting a bit technical but I notice you have the rear "pulling" spokes laced heads in then interlaced under the crossing spoke by the derailleur. When the rear derailleur is on the big sprocket I'm wondering how much clearance you have between the derailleur cage and the spokes. I just built up a set of traditional 3x wheels using Record hubs and Nemesis rims with DT Comp spokes (which are of coursre thicker than your flat CX Rays), but I wanted to test how much clearance there would be with the 11 speed Campy. I built it up, slapped on a cassette and put it in my C59. The clearance was just too small for my liking and I got to thinking that a hard effort up a hill or in a sprint may just be enough to pull the crossed spoke into the derailleur. I mulled it over for a few minutes then decided it wasn't worth it to find out and rebuilt the wheel with the pulling spokes heads out to avoid this. Gave it a bit more clearance and piece of mind for me. I was also considering using the new CK campy hubs for this build, but it's kind of a classic so I went with Campy Record.
Love your photos by the way, very detailed.
Thanks for the comments! I built up the wheels myself. At the risk of not sounding detail oriented, that wasn't something I actually considered when building. I've built up 6 or 7 wheelsets but never really had to worry about any tight derailleur clearances so not something I even thought to consider beforehand. In my head I am trying to picture reversing the heads in/heads out and trying to picture how it would affect the clearance but its hard without seeing it. Had I read your post, prior to building the wheels I probably would have put more thought into this aspect of the build (so I am thanking you for the advice for my future wheel builds ). That said, there aren't any clearance issues. There is about 2mm at least at the closest part of the derailleur (right in the center of the upper jockey wheel), and it lines up right around with the spoke cross. I haven't had any issues yet. Makes me want to give it a go on a steep climb to see if it poses a problem.
Being that this is my first venture into Campy, and of course 11 speed, what is acceptable or "normal" clearance from the cage to the spokes? Is this 2mm a cause for concern?
