IMPROVED BICYCLE REAR SUSPENSION SYSTEM

摘要

A bicycle rear wheel suspension system configured to provide a rear wheel axie travel path having a relatively large rate of chainstay lengthening in the first part of the vertical rear whee! travel and reduced chainstay lengthening in the latter part of the vertical rear wheel travel, so that the overall change in chainstay length is small relative to the amount of vertical rear wheel travel. The system provides the rear wheel axle with a nonarcuate travel path such that the rate of change of a shock rate, where shock rate is defined by a change jn shock length over a change in rear wheel travel distance, changes sign at feast twice over the travel path.
