Seat pin arrangement for bicycle, mountain bike, etc - has guide tube and tubular seat pin, and spring arrangement between them, for elastic support of saddle carrier

摘要

The arrangement consists of a guide tube fastened to the bike frame, and a tubular seat pin, which slides axially in the guide tube. A spring arrangement is located between the two, and one end of the seat pin projects from the tube. A saddle carrier is connected to the end of the seat pin, so that a limited relative movement between the two is possible in a direction mainly parallel to the forward/backward movement of the saddle. A bearing arm is integral with the guide tube nad a pivot arm is integral with the saddle carrier, and has a front end, which is connected pivotally to the bearing arm. ADVANTAGE - Simpler construction, smooth damper action.
