ABSTRACT:
A heat dissipating arrangement for a damping system, such as the damping system of a bicycle suspension fork. The heat dissipating arrangement includes a heat sink, which, in a preferred embodiment, has a substantially cylindrical body and radially extending heat sink fins. The heat sink is either positioned over or around a damping cartridge or other damping system containing damping fluid or is formed as the damping cartridge itself. Preferably, the heat sink is positioned within the inner fork tube of a suspension fork with the heat sink fins in close proximity, and preferably contacting, the inner wall of the inner fork tube. Thus, the heat sink fins dissipate heat from the damping system to the inner fork tube. The pumping action of the suspension fork, as well as air passing over the fork as the bicycle is moving, dissipate heat from the fins, and thus from the heat dissipating arrangement and the damping system.
