Often the seatpost and handlebars are a really cheap place to save weight. You could pull those off and weigh them then compare to some specs on after market parts. That crankset and bottom bracket is also likely a huge piece of the weight.
The trouble with trimming bike weight is that the weight is usually distributed all over the bike. You probably are in a good place with the frame and fork though. I would expect that you could get that down to around 23 pounds without and extremely high-end parts.
