The frame is about a pound heavier. The VISP is all thick straight gage tubing, sort of like an aluminum equivalent of a cheap hiten steel frame. The Leaders are butted tubing and a lot lighter. The VISP fork weighs close to 2 lbs, and has a steel steerer tube. My 721 bike with a full carbon fork is 2-1/2 lbs lighter than the VISP (16.5 .vs. 19.0 lbs), but the 721 also has some light carbon bits on it as well.
