It always amuses me how that people will spend big money to drop a few ounces from their bike and then add two (or four) full water bottles that must weigh a couple of pounds! Making sure that your bike fits properly will also make you more efficient and add speed.
Since I really can't drop much more weight from the engine, you have got to start somewhere. Water is water, it weighs the same no matter where it is, in you or on you (a pint a pound the world around). Can't ride without it so it is fixed into the equation. You know what else, you are going to carry that water with you whether or not the bike weighs 40 pounds or 35 pounds.
Bike fits, and has basically the same setup as our single bikes with the exception of captain saddle to bar drop. Saddle to center of cranks are exact, setback is exact, saddle to bar is exact, can't get much closer than that. I could flip the stem and get more aero but it is certainly easier to control the bike sitting just a little more upright!
The disks are heavy, about 120g per caliber and an additional 220g per rotor, that is without bolts, brackets or pads. I could go to some canti's and be down in the 160-180g range with everything for just a few dollars on ebay.
