I'm not going to read through the whole thread so this my be redundent but 1/3 of a pound here and another 1/3 there and soon you've lost a pound. My LOOK 595 was a shade over 15lbs, not exactly a heavy weight. I changed out bars stem saddle and now it's just under 14lbs. It all begins to add up and make a difference. I'm pretty much at a point that if I lose any more body weight it will affect my power so the weight had to come off the bike.
