Just another update on this one as I continue to mess with it before deciding on the build. The wheels,tires, and cassette on this were really heavy! It was weighing 23 lbs and 1 oz with them. A quick temporary swap to some Campy Eurus wheels I had on hand with a Record 10 speed cassette and Conti GP4000S II 700 x 25 tires dropped it down to 20 lbs 5 oz. Swapping in a preferred Fizik Kurve and Thomson seatpost now has it at 20 lbs 1 oz. That's quite a drop with no carbon fiber involved. Should feel more lively on the road today with the changes.
This is more along the lines of what I expected with a Columbus EL OS frame.
