Shimano Tourney TZ RD-TZ500-GS is a medium-cage rear derailleur designed for 6-speed drivetrains on urban, recreational and entry-level mountain bikes.
Key Features
Construction and Design
The medium GS cage maintains suitable chain tension in drivetrains with a total capacity of up to 34 teeth. Two 11-tooth pulley wheels guide the chain smoothly during gear changes.
Its durable construction is designed for everyday use and straightforward maintenance. An integrated cable adjuster allows the shifting setup to be fine-tuned.
Main Functions
The Shimano SIS indexed shifting system allows each gear to be selected with a defined movement of the shift lever. When correctly installed and adjusted, the derailleur moves the chain consistently between the rear sprockets.
The derailleur has a total capacity of 34 teeth and supports a largest rear sprocket of up to 28 teeth. The maximum permitted difference between the front chainrings is 20 teeth.
Use and Compatibility
The RD-TZ500-GS is officially designed for Shimano SIS 6-speed rear drivetrains. It is compatible with HG-type 6-, 7- and 8-speed chains, although the number of available gears depends on the complete drivetrain and fitted shifter.
The derailleur supports conventional direct attachment or installation using a suitable adapter. The bicycle’s mounting type, rear sprocket size and shifter compatibility should be checked before installation.
Additional Features
The derailleur belongs to Shimano’s Tourney TZ series, which is designed for practical everyday drivetrains. It is suitable for urban, hybrid, recreational and entry-level mountain bikes.
Summary
The Shimano Tourney TZ RD-TZ500-GS is intended for cyclists who need a straightforward rear derailleur for a 6-speed SIS drivetrain. Its medium GS cage, 34-tooth total capacity and integrated cable adjuster make it suitable for everyday riding and replacement of a worn derailleur.
