Hi...I ride a 2000 Cannondale Jekyll 700SX, which has the single pivot swing arm (same arm that the Super V had). Later generations of the Jekyll had a different swing arm, and I was wondering why they decided to make this change. What is the advantage of this other geometry (strength? weight?)? If one wanted to, could you place the swingarm from a new Jekyll onto a '00 Jekyll? Would anyone reccomend doing this? Thanks for the help!
