What Is the Shimano Tourney SL-FT55 Right Thumb Shifter For?

The Shimano Tourney SL-FT55 is a 7-speed right thumb shifter for flat-bar bikes, using a traditional push-button mechanism with an optical gear display that shows the current rear gear position at a glance. The optical display is particularly useful for recreational riders and commuters who want instant gear confirmation without counting clicks -- a simple visual readout makes it clear what gear you're in at any moment. Sold as a right-side unit only, it controls the rear derailleur on 7-speed Shimano drivetrains.

Compatible with Shimano 7-speed rear derailleurs and drivetrains. Right side only. Cable not included. Flat bar mount. A practical replacement option for entry-level and utility bikes running 7-speed rear systems.
