Well, after many months of planning, here it is.
56cm
On shop scale it was 13.1 lbs.
Put in XXX race lite tubes shaving 70grams
Replaced "sizing" alloy spacers w/ the stock carbon and removed 20mm of steerer to start.
Took off a bit more than 120 grams w/ those changes dropping it under 13lbs (then put it right back on w/ cage and Cateye).
Hope you enjoy the finished result.
