I don't really have an exact number. I was just curious. And....why is it a bad idea to go under 1500g? I'm sure I could make my Trek lighter by switching some components but thought a new build up with all light stuff could be fun. Not that I'm in a financial position to start it soon, but I'd like to start thinking about it now.
