The bike is beautiful out of the box and is well spec-ed, especially for under 2K. The frame is very muted and yet not wooden: it jumped when you accelerate uphill and feels light. Descending is a joy even though the head tube on the 51 I bought was far too high even with a -10 stem for someone used to a greater drop (the FSA wing Compact while a great bar doesn't help here as it's drop is 20mm less than my current bar making my torso position that much higher). I was not a fan of the setback with the included (and lovely aesthetically) 20mm set back FSA SLK carbon post but I think that this frame was a touch large for me (6ft with a 34 inch inseam and longish arm).
For all these reasons I sent the bike back and am ordering the 48 as the head tube is 25 mm shorter and the setback a bit less. Still I imagine I will want a 0 mm setback post with this frame. My current bikes are more conventional shaped frames without the sloping top tube, but I still like this bike a lot and if the size is right I think that it could be a great bike. It doesn't feel like a comfort bike like the Synapse or (gasp) Roubaix and the tubes are beautifully shaped. It's only too bad that it's not the Campy version on sale!
