I like my aero, but I like it light as well. I started out with a 2008 Soloist Carbon. It developed a crack in the top tube, and was warrantied for a 2011 S2 replacement. It was down to 13.3lbs or 6033g at one point, but after some changes in my fit going to a longer stem, and shorter shallower drop bars, it gained some weight up to 13.5lbs or 6124g. I am now trying to get it down under 6000g is the goal, or ultimately sub 13lbs, or 5896g would be nice too.
Last pic of the old bike before it perished.
Most recent pic of new build. Right about 13.5lbs as pictured.

I just bought a set of Zipp Vuka Sprint handlebars for the build to replace the heavy FSA bars. The FSA bars were supposed to weigh 210g, they weighed in at 271g, then I cut 8g off of the ends of them. The new Zipp bars are supposed to be 210g as well. I am hoping I get lucky, and they are somewhat close to that. I am also hoping for an increase in stiffness, for the FSA bars flexed a lot more than my older Syntace Racelite Carbon bars, that I had on there. Next on the list is a new stem. I am on the fence between Extralite, and New Ultimate. Either one should net a good bit of weight savings. I've been kicking around the idea of a custom 1 piece saddle, post, and Fibre-Lyte rings as well. I also may further tune the Red RD, and lighter tires are going on over the winter too. I am thinking Vittoria Corsa Evo of some variation. Thoughts, ideas, and advice welcome.
