Lefty is a unique design of front shocks by Cannondale. Unconventional might be an understatement, but by using just one leg (Arr!) the design is lighter and stronger with a "square-in-a-square" that provide no play in the shock tubes. The forks are sealed interally and externally to provide the longest shock life imaginable, and rider peace of mind.
