Frame #2 Four Months of Testing

It's been far too long since I last posted.  In the mean time I completed frame #2 about three weeks after the first one and I've been test riding it ever since.  It has about 2700 km on it on mostly paved roads, rollers, some gravel roads and some less than gravel twin track roads in the Appalachians of North Carolina near West Jefferson.
I built the bike with an EDGE 2.0 fork, Shimano Dura-Ace Di2 groupo, Ritchey WCS stem and post, a Pro carbon bar and Shimano 7900-C24-CL wheels. 
It has internal Di2 wiring and an under down tube battery mount.  The frame has a "lugged" look to the joints rather than the smother finish on the first frame.  The finish on this is spray can automotive clear coat.  I have an interesting finish idea for the next frame and it will have the proper logos etc (now that I know the frames work).
It's been ridden hard and has held up well.  No frame related issues of any kind.  At first I though the back end was a bit too harsh but I think that was just in contrast to the True Temper S3 frame I'd been riding for years.  I used the BB86 or press fit Shimano standard for the BB.
I'm planning the next version of this frame with a lighter chain stay assembly and thinner individual seat stays.  This should bring the weight down from the current 1060g for a 58.5cm frame.  I'd like to do internal rear brake cable as well as Di2 wiring.
