Top pull type front derailleur

摘要

A top pull type front derailleur is designed to move or shift a chain between two or more sprockets for changing gears. The front derailleur basically has a bicycle frame clamping band, a linkage assembly and a chain guide. The linkage assembly includes a cable connection point and is arranged between the bicycle frame clamping band and the chain guide to move the chain guide laterally towards and away from the clamping band. The clamping band has a top pull cable guide surface that is configured and arranged relative to the clamping band to guide a cable from vertically above the clamping band to the cable connection point when the front bicycle derailleur is operatively mounted to a bicycle frame. Preferably, the top pull cable guide surface is formed on a peripheral surface of a roller that is rotatably mounted on the clamping band.
