摘要

A spring system (1) comprises a first load applying portion (22) and a second load applying portion (26). First spring(s) and second spring(s) are located to act between the load applying portions. A piston(s) (36) is located between the first and second springs (10, 12, 14, 16) and is movably received at a housing element. The housing element consists of a fibrous composite material. The first spring is a pneumatic spring and the interior wall of the housing element forms the bearing surface of the piston which seals the pneumatic spring. An independent claim is also included for a suspension fork in particular for bicycles comprising a fork and at least one spring system.
