Shifter Microshift MSH-TS38-7R, right-hand 7-speed thumb tap, Shimano-compatible, gear indicator

Microshift MSH-TS38-7R is a right-hand bicycle shifter designed for 7-speed indexed drivetrains and compatible with Shimano-style systems. The unit uses a thumb-tap actuator to change gears and includes an optical gear indicator that displays the selected cog. Intended for use on rim-brake and compatible hub setups that accept 7-speed indexing, this shifter provides simple, mechanical shifting control for commuter, city and casual bicycles.

Advantages

The thumb-tap mechanism allows fast, one-handed shifts with clear tactile feedback without requiring complex setup. The integrated optical gear indicator gives a quick visual reference of the current gear, useful when riding in traffic or on unfamiliar routes. Compatibility with Shimano indexed 7-speed systems and a compact right-hand design make the shifter straightforward to install and replace on many standard handlebars.

Suitable for

• 7-speed commuter and city bicycles
• Casual and leisure bikes with indexed 7-speed drivetrains
• Rim-brake bikes and hubs that accept 7-speed indexed shifting
• Riders who prefer thumb-operated shift controls

Key specifications

• Side: right-hand
• Speed compatibility: 7-speed indexed
• Actuation type: thumb-tap (thumb shifter)
• Compatibility: Shimano-style indexed systems
• Display: optical gear indicator
• Mounting: handlebar clamp compatible with standard bicycle handlebars

How to use

Install the shifter on the right side of the handlebar using the clamp and secure it to a comfortable thumb position. Route the shift cable to the rear derailleur or compatible hub following manufacturer cable routing guidelines, then set cable tension and indexing to align with the 7-speed cassette or hub. Use the thumb-tap lever to shift up or down through gears; the optical indicator will show the selected gear. Periodic cable tension adjustments and routine inspection of the housing and cable ensure reliable indexed shifting.

Usage recommendations

Use compatible 7-speed indexed derailleurs or hubs and Shimano-style cables and housings for best performance. After installation, fine-tune cable tension and indexing with the bicycle on a stand or supported so the rear wheel can rotate freely. Replace frayed cables and corroded housings to maintain crisp shifting and accurate indicator readings.
