Claims20
A spring system for bicycles, comprising:
- a first load-applying segment and a second load-applying segment;
- at least one positive spring and at least one negative spring arranged to be operatively effective between said first and said second load-applying segments;
- and
- at least one full floating piston between said positive spring and said negative spring;
- a first cylinder extends axially displaceably in a second cylinder;
- said at least one full floating piston being moveable relative to said first cylinder and said second cylinder;
- wherein said positive spring and said negative spring load the full floating piston axially in opposing directions;
- and wherein said positive spring and said negative spring load said second cylinder in opposing directions;
- wherein said full floating piston is supported at a radially outer situated surface of a casing wall of said first cylinder;
- and
- wherein said full floating piston projects axially from the end of said first cylinder facing said second cylinder.
