I am seriously considering buying a 2004 AC 2. I have been at the local dealer and have been test riding the trek liquid 25 and giant VT 2 to get a feel of the fs since there are no AC bikes are available to test ride. I have to admit, these bike are totally awesome. The dealer seems to favor the VT 2 over the liquid and since there is no AC to test ride or even see, it is kind of hard to determine if the AC is best for me. I am 6'3" and weigh 200. I am an extremely powerful rider who wants to have the option to take big jumps if the opportunity is there, yet be able climb and enjoy various trails I may encounter. Does anyone know the weight difference between the VT 2 and AC 2? Another concern I have is that the largest frame size for the AC is 19". I am 6'3" and am used to riding a 21.5" frame. Will the 19" frame work for my height? Thanks!
