Abstract
A guide pulley mounting mechanism for use with a bicycle derailleur. A rear take-up pulley is mounted to a plunger rod that travels within a plunger frame in a more or less horizontal arrangement with respect to the bicycle frame. A bias spring mechanism urges the rear take-up pulley in an outboard direction such that tension is maintained on the chain as different main gear sprockets are selected.
