...than my S-Works E5 frame. Is this a huge difference considering that I weigh 188 lbs which would translate into .25% increase in weight if you add my weight(188) plus 16-17 pounds in the bike. The Tarmac Comp is supposed to be a stiffer yet smoother riding bike. At what point should one worry about having a heavy bike? My bike with full Campy Record,CR420 wheels, WCS Fork,WCS Stem ,bars,post, Tarmac Comp Frame should still come in at 16.5 in full race trim.
