## Summary description

Microshift left-side shifter MSH-TS39-L is a 3-speed thumb-tap gear shifter compatible with Shimano systems. It features left-hand mounting, an optical gear position indicator for quick visual reference, and Thumb Tap actuation for precise, ergonomic shifting. Intended for bicycles requiring a dedicated 3-speed left shifter and suitable for replacing or upgrading compatible drivetrains.

## Long description

Microshift MSH-TS39-L is a left-hand 3-speed thumb-tap shifter designed for use with Shimano-compatible drivetrains. The unit mounts on the left side of the handlebar and provides precise, incremental shifting for three front or auxiliary speeds. An integrated optical gear position indicator gives a clear visual reference of the selected gear, while the Thumb Tap mechanism allows ergonomic, responsive actuation suited to a range of bicycle styles that require a dedicated 3-speed left shifter.
Advantages
The shifter's Thumb Tap design offers short, definitive lever travel for accurate shifts with minimal hand movement. The optical indicator provides immediate visual confirmation of gear position, reducing the need to look down while riding. Compatibility with Shimano-style systems simplifies installation and replacement on bikes using similar shift cable pull ratios. Its left-side mounting and compact form factor help preserve cockpit space and maintain comfortable control ergonomics.
Suitable for
Road, hybrid or city bicycles that use a 3-speed left-side shifter
Bikes with Shimano-compatible front derailleurs or auxiliary three-speed setups
Replacement or upgrade of existing left shifter units
Riders seeking a simple, mechanically reliable thumb-tap shifting solution
Key specifications
Shift type: Thumb-tap actuation for left-hand use
Number of speeds: 3-position indexing
Compatibility: Designed for Shimano-compatible cable pull systems
Indicator: Optical gear position indicator for visual gear display
Mounting: Handlebar clamp for left-side installation
Form factor: Compact housing to reduce handlebar clutter
How to use
Install the shifter on the left side of the handlebar using the supplied clamp or a compatible clamp size, then route and secure the shift cable to the front derailleur or three-speed mechanism. Use the thumb tap lever to shift up or down through the three indexed positions; the optical indicator will display the current selection. Adjust cable tension and limit screws on the derailleur as required to ensure precise engagement across all three positions. Periodic cable lubrication and inspection will help maintain smooth operation.
Usage recommendations
For best performance, pair the shifter with a Shimano-compatible front derailleur and matched cable and housing. Verify correct cable routing and tension after installation and make fine adjustments while stationary to avoid chain drop. Inspect the optical indicator for dirt or obstruction and clean as needed to keep gear position visible.
