Ya - Frame came pretty quick. It showed up a day or two after I ordered...can't really complain.
Was initially planning to upgrade over winter. But then while looking at pictures online I stumbled across a 58 FRD frame in stock at Irvine Cycles, and was waffling between getting an AR3 and probably putting Dura Ace on it vs waiting and ordering an FRD for '15. I asked the local shop if they could get the 58 from another dealer, and he checked Felt's stock on the FRD first, and saw there was one available. I ordered it on the spot Long story short, I feel like I got lucky with availability....and am building the FRD with ultegra rather than an AR3 with dura ace - should come out about the same initial weight.
I'm replacing a venge and a tarmac with the AR - nice to see that others have done the same and are happy.
I have also been slowly picking up 6870 parts in anticipation of a build. Was contemplating going with 9070 shifters as that would save ~75g. But not sure I can justify the price difference it would cost. I was able to pickup the 6870 shifters new for $180 with a discount I had. Cheapest 9070 shifters I have been able to find is ~$500. $320 to save 75g, comes out to $4.27/g.
It must be the angle of that picture but I thought the downtube was dropped closer to the front wheel. That picture for some reason makes it look like a fairly large gap.
SuperDave mentioned the weight as being around 900g and fork 325g for the AR FRD in a target size 56.
MODEL FRAME / FORK
AR FRD 900g / 325g
AR1, AR3R 1050g / 350g
AR2, AR3E 1000g / 350g
AR4, AR5 1100g / 375g
Surprised to see FRD at 1037g/334g.
A AR1 posted earlier came in at 1071g/335g.
But at the end of the day, why do I want a TeXtreme carbon fiber bike and not one made from UHC Advanced MMC carbon fiber?

Is it really 7-10 watts (70-100g) just for mechanical cables and the airflow disruption that causes? The AR has a total drag of 600-700g, just surprised that 10-17% of the frames drag could be related to just going mechanical over Di2.

Frames like the Giant Propel and the Cervelo S5 have flared air foil down tubes to accommodate bottles. Was any of your wind tunnel data with bottles on your frame as well as your competitors you tested (Giant , Cervelo, Scott, etc.) ?
Any ideas on this one? I haven't seen an answer to this. Based on the shape of the downtube, I assume it was not optimized for bottles and cages in place. I assume Felt will add this feature on the 2016 or 2017 AR frame?
So far have a AR FRD in at 1037g/334g, the above at 1052g/328g.
At those weights, the AR1 frame sets seems like the clear bang for the buck.
Weight of the frame (58) was 1100ish. But I didn't pull out the bolts, derailleur hanger, grommits, or the liner that was run to ease cable runs. Sorry - I was in a time crunch to get it up and together for my Saturday morning ride. The bottom bracket shell is a nice piece of machined carbon - Seemed a bit scary to press fit the bottom bracket directly into the frame, but it worked just fine. Fit/finish on the frame is excellent. Carbon spacers, headset, bearings all worked as expected. I suppose I should have weighed them to compare to the non-FRD versions. There wasn't enough room for a cadence magnet for the SRM on the outside of the bottom bracket shell, so I glued it from the inside through the little di2 hole. Looks/works perfectly. Seatpost clamp is a cool piece of engineering. It clamps down vertically while tightening it horizontally - clamped my 7x9 rails just fine.
Seatpost was 248g, including the bracket that functions as a collar, and the di2 hanger. Fork was 334g uncut. Cut down to 309g with 15mm of spacers. I'm running 5mm above the stem still - might end up 5mm either way for final fit.
ultegra di2 w/ sprint shifters (fd is dura ace, because I couldn't get the ultegra one quick enough),
Specialized s-works crankset with an SRM spider / praxis 39/53 rings
KMC X11 Chain (not an SL)
SRAM XG-1190 11-26 cassette
november rail 52mm wheels
running normal shimano brake cables,
planet-x CNC front brake,
ultegra direct mount rear brake BR-6810,
3t ergonova pro bars 42cm (on my list to upgrade)
Lizard skins dsp 3.2 tape
3T arx II team stem (110mm)
Fizik Antares 00 saddle
Specialized rib cage carbon knock off ebay cages
I'm planning on replacing the bar / cables pretty shortly, which should drop it under 7kg. Beyond that, the $/g ratio of my build gets prohibitive I'll also be replacing some bolts / other miscellaneous stuff with red anodized bits: I've got a k-edge chain catcher on order.
