Since I'm racing for local BMC dealer the new bike needed to come from BMC brand. SLR01 is way to expensive and SLR02 is very similar to SLR01, the problem was that SLR02 is not sell as a frameset. So I have bought SLR02 Ultegra, because of nice colour scheme. I have stripped everything down and starting to build my own bike. It is a bike for racing - I wanted for the parts to be reliable, stiff and relatively cheap. So no carbon handlebars or stem.
Groupset needed to be electronic - I was on my 7970 Di2 for too long. Every time I needed to switch for a manual gruppo I appreciated how great the Di2 actually is. You dont even know that there is something like FD/RD and you can completely focus on the race. Ultegra Di2 6870 is probably almost as good as Dura-Ace, but from my experience Dura-Ace will handle racing demands much better. And the look of 9070 is simply stunning.
I was disappointed with my Zipp 404 - I mean the rims are awesome. I even love the way the 404 looks and what a sound they make, but the hubs? Oh god, never again. It was the old model from 2011, but friends had problems with 2013 hubs as well. So I was looking for something more bombproof and hopefully more rare. Contacted local dealer for Veloflex/FMB/A. Dugast and I have actually discovered he is selling Corimas as well. Get better deal on "S" version (Different hubs and spokes) and I they are great. Stiff, butter smooth hubs and handle road buzz quite well.
Didnt really have a time to make nice photos, so just this crappy one.
The parts eventually shape up like this:
BMC SLR02 57
Dura-Ace 7900 SRM 53/39 (7800 Arms)
Shimano Ultegra 6800 11-25 // Shimano Dura-Ace 9000
Shimano Dura-Ace Di2 9070
3T Rotundo 42cm // 3T ARX 130 -17°
Selle Italia Flite Flow // BMC 18mm setback
Shimano Dura-Ace 9000 // SwissStop Yellow FlashPro
Corima Aero "S" // Veloflex Roubaix 25
Corima Aero "S" // Veloflex Roubaix 25
Computer mount: FlyBar 2.0 for Garmin
Tape: 3T Team Tape
Bottle Cages: Tacx Tao
Hope you like it!

So when it's a BMC frame it is an even more awesome bike.
With beige tubulars damn, ice on the cake.
I would like to drop some weight from the build as well, definitely there is opportunity in the crankset (probably switch to 9000 crankset with Stages). Also cassette could be switch to Dura-Ace, but I don't think price is worth it. Or where do you thinks I could save a big chunk of weight for relatively little money? I guess in details and small parts...
Veloflex Roubaix is great tubular. Really grippy even in wet conditions and so comfortable - love the gum sidewalls. Normally I'm using heavy clinchers for training, but now I'm considering some low profile tubulars with high spoke count hubs. Any ideas, preferably relatively cheap?
I have tried to make some better pictures. Little teasing below. More on my Flickr.
In terms of cheap(ish) low profile tubs I would have thought something like Ambrosio Nemesis rims on Shimano Ultegra hubs would be good. I recently had a set built onto Campag Record hubs and have been very impressed.
Corima Aero S
Ride quality - Corima is really a comfortable wheelset. The first thing I have noticed is how good they feel on rough roads. They simply don't transfer the road buzz and make almost no noise on bad surface. Corima is filling the rim with foam and this is probably the reason why they feel this way. On the other hand they still feel responsive and you don't have a dull feeling. I used to ride Zipp 303/404 and Corima beats them easily in quality of the ride. When cruising at high speeds they barely make a noise, but the distinctive “vooosh, vooosh” is still there when you start swaying bike from side to side.
At speed - The wheels roll nicely at high speeds and I didn't have a feeling of being slow. Zipp 404 are probably faster in aero lab, but the differences will be marginal. On the other hand I found them more enjoyable in crosswinds than Zipp’s. You can definitely feel that you are on deep profile wheels, but Corima are really easy to handle and act predictably. You can feel the constant push from the rim, but the sudden gusts are almost eliminated. The internal nipples are helping to lower the drag and keeping the clean look, but its just a pain in the ass to service, especially on tubular rim.
Climbing/Sprinting - Aero S are really stiff wheels. It is almost not possible to rub the brake pads and I found my self enjoying sprints much more. They are firm and joy to climb in big ring, yet they don't jump around on bad surface under power. Even when pushing 800+ watts there is almost no flex. The weight of the wheelset is reasonable and they feel nice when changing the pace when climbing. The hubs are butter smooth and the wheels has almost no drag and its really easy to spin them. Sudden accelerations are something when they really shine.
Braking - The Corima red brake pads are included and should be used. SwissStop Yellows are offering more raw stopping power, but its harder to modulate it and you can feel a small pulsation under heavy braking. The red pads on the other hand offering amazing braking consistency and power modulation. The brake pulsation is completely eliminated when using Corima’s brake pads, so does any noise when braking. The same applies for wet conditions - lacking a stopping power, but the sudden break application, once the rim gets dry, is almost eliminated. They feel predictable when breaking and are really stable on long descent, even in wet conditions. The overall braking distance seems to be little longer, but I have find myself feeling more confident when braking, especially in the bunch, with Corimas than with Zipps.
Details - The hubs are incredibly easy to service, roll with no drag and are beautifully made. Cassette bodies are changeable with hands only and there is no need removing a cassette from the hub body. Which is great for someone owning two bikes (SRAM/Shimano and Campy). There is also no noise from spokes crossing, which sometimes cannot be said about different wheelsets. The Corima's looks is really a distinctive thanks to the unique carbon wave and clearly they attract attention.
Would love to answer you questions!
