What Is the Shimano ST-TX800 Tourney TX and Who Is It Designed For?

The ST-TX800 is Shimano's Tourney TX series integrated brake and shift lever set for 8-speed flat-bar drivetrains, occupying a step above the base EF41 and EF500 series in build quality and lever feel while remaining in the entry-level price range. The set combines Shimano SIS index shifting with a reach adjust mechanism that moves the lever blade position relative to the handlebar to fit different hand sizes, and includes an Optical Gear Display in each lever body that shows the current gear as a numbered readout. Available in both black and silver finishes, the TX800 is one of the few integrated lever sets in the Shimano lineup with a color option, making it a practical choice for riders who want their control levers to match silver-accented component builds or city bikes.

The ST-TX800 is compatible with Shimano 8-speed rear drivetrains using SIS indexing and standard front derailleurs for double or triple chainring setups depending on the left lever configuration. It is designed for flat-bar use and is compatible with V-brake and linear-pull brake systems. For riders building or restoring a flat-bar Shimano Tourney TX 8-speed drivetrain who want a clean-looking integrated lever set with a gear indicator, reach adjust, and the option of a silver finish to match classic or urban component aesthetics, the ST-TX800 is the correct specification.
