I use two identiacal bathroom scales, one wheel on each and one foot on each when I weigh myself. A few years ago I weighed less than my bikes and now I weigh more. So relativly speaking my bikes are lighter compared to me.
Let's see...improve diet+offseason conditioning+less alcohol= 30 lbs less bike weight. My guess is the bike is going to stay the same weight. Just concentrating on off season conditioning will have to be enough to horse the scoots around.
