So--At long last I am back and picked up the carbon wheel/rim! Fortunately, the post office was able to hold it for two weeks for me no problem.
First impressions, the rims are gorgeous. Looks exactly as shown in the previous pic, with the exception of silver nipples. I also observed the rear wheel (assembled) seems to be built quite well. The tensions are fairly consistent and the rim is dead true/round. I will be lacing and tensioning the front rim this weekend.
Weights:
Front rim (bare) 752g. This is a little more than I expected but still quite light.
Rear wheel, assembled (no axle) with Sapim D-LIGHT spokes, Novatec 202 hub and Shimano freewheel: 1370g
Front wheel, unassembled but with the hub, same as above spokes and nippes: 1170g
This gives a wheelset weight a little higher than advertised (2440g versus 2540g actual). Perhaps this is due to the 3K versus UD selection or mfg variance? An astute reader might note that I'm using a different front hub than shown on xmcarbonspeed.com, although mine is still the same model Novatec and is narrower (135mm vs 150mm). I also ended up with lighter spokes than "stock", the D-LIGHTs are supposedly ~50g/wheel lighter per wheel.
Regardless, I am now able to assemble the bike and will update you guys when I can!
Cheers
