It could have a linearity issue??

EDIT: I just weighted a piece of electronics equipment that the service manual indicated weighted 26.4lbs. My digital scale read 26.72. So yes a little bit higher, but not that far off. I weighted the BS500 again and indicated 26.1 this time, maybe I had the water bottle on it last time. So if I subtract the potential .3 lbs of scale error based on my earlier equipment measurement it still places my bike at around 25.8lbs, a little over 3 lbs heavier than yours KB.

EDIT 2: I notice the BS ad above indicated the 23" bike was 25lbs. If I subtract the weight of little accessories I might actually be really close to that 25lb mark. I'm not sure how much additional weight is subtracted going from a 23" to 21" frame though.

EDIT 3: Just for comparison sake KB. My front wheel weights 3.58lbs w/skewer. Comparing that to yours will tell me how much heavier my rims and hubs may be.
