Thanks guys!
Bykemike: What bottom bracket, specifically, are you running? How much does the Stronglight with that BB weigh?
Veganbikes: Thanks for the suggestion, and you are right, this is 100% a "light, but still reasonable..." build. With some custom hill climb wheels and the Undefeated frame, I've got a brainstormed build at around 5800g for a little over 2k. Without spending a bunch--like A BUNCH--more, I don't think I am getting much lighter than that.
I can hear the true weightweenies scoffing at me...
