The Shimano TOURNEY TX ST-TX800-L shifter is designed for 3 front speeds. It has an optical gear display and adjustable reach.
OPTICAL GEAR DISPLAY – the optical gear display shows the selected gear position while riding. It lets you see how many gears you can select in either the lower or upper direction, making shifting easier to control.
SIS INDEX SHIFTING SYSTEM – the system components—the index mechanism built into the shifting lever, the frictionless SIS Rear Index Shifting cable and the smooth-action rear derailleur—make up the SHIMANO INDEX SYSTEM.
