That's pretty respectable in my book, considering the bike's intent. I do not know the apportioning of weight between frame & fork of CF bikes, as they don't interest me much.
My payload for commuting has been north of 20lb sometimes, so for me the weight savings of a high end frame is fairly pointless; I could get more benefit by just paring down my payload, if I wanted to. But, since a large part of the reason I bike commute is exercise, there's little incentive to go all weight-weenie on my commuter bikes. Of course speed is also a consideration, but +/- a few pounds on a gross weight in the vicinity of 200lb does not lend itself to a measurable difference in total elapsed time. Putting it another way, there's a lot more to be gained speedwise, at least in my case, by improving and/or lightening the "engine" than by incremental weight reduction of the bike + equipment.
