With two water bottles my race bike weighs almost 23 lbs.
In college, when I won our conference championship and overall my bike weighed closer to 24 lbs. With nothing aero anywhere (aero hadn't been invented, yet. ;D).
Like I said in two or three of the very first threads you made, you have to learn how to ride efficiently in a pack. Basically you need to be invisible. That's the only way you're going to survive these races at your current weight and power output.
