No bottles. IIRC and probably weight accuracy is plus or minus ½ lb. I don't really obsess over knowing weight to the tiniest gram. It's just for rough comparison.
Will that do?
Thanks. I guess that 6lb. weight drop (>25%) does translate into some performance gains. My present bike is 27lbs. and the bikes in my price range (Trek Domane) are about 22 lbs. I wonder how much difference I'd feel, all else being equal.
