Cant tell you why but this wheelset makes the old hair on the back of the neck stand up.
I think its because they are as good as it gets, I have built a couple of wheelsets which have been used on the Paris Roubaix pave one set was Ambrosio Excellence and the the other were Ambrosio Nemesis, they were not laced to anything exceptional as far as hubs concerned in fact I think they were Novatec classics and Zenith which are Novatec, I aonly use Sapim spokes double butted. Both riders reported back excellent results, the Nemesis rider having not ridden on tubular before was blown away on the smoothness and acceleration of the wheel and tire combination , a common denominator it seems when riders speak of this wheelset.
Nemesis has been around a good many years now and has a quite respect of being the wheelset of choice for the Paris Roubaix and it seems judging by this few posts I have found that this choice is pretty much agreed upon.
I have extracts and links in this post so if its yours and you dont want me to use it please email me and I will remove it.
I can build and supply pretty much any combination for the Nemesis hub wise and spoke so let me know shedborn@gmail.com

Written word
These are pretty much the best alloy tubular rim available today, and certainly in a box-section profile. They are immensely sturdy, not unreasonably heavy, build up beautifully, and are superbly finished cosmetically. I don’t think I’ve ever seen a Nemesis fail, short of a crash where it was run over by a car.
A special feature of these rims is that they lace up into a wheel that is both immensely strong and also has a suppleness to it that, like a good frame, takes out the harshness of bad roads. Don’t do anything fancy with them, just a basic 3-cross lacing all the way around with DT Competitions or an equivalent spoke. This isn’t a place to use aero spokes or lightweight spokes or spoke counts. The rims used to come in 28, 32, and 36 drillings, but the 28’s have been discontinued and the 32’s are a bit easier to find than 36’s. I personally keep a stash of the 36’s. For long training rides you’ll really enjoy the feeling of these rims.
The finish is very durable, even on the braking surfaces. The tire bed is really well shaped for most tires from a 22 to 28 mm or for cross tires (which don’t fit anything all that well, so it’s relative).
The Nemesis has been around for about 20 years, and the alloy in the rims has changed a couple times. The best are the current version, which was in a greyish-brown color with a script silkscreened “Nemesis” and no actual stickers. This version was changed slightly to a darker grey with some extra lettering, but it’s the same rim underneath.
If the Nemesis is way overkill (and for a 140 lb rider it may well be), you can get the same rim in a lighter build in the Ambrosio Crono. Be sure to get the current version; older ones were rather.
