Microshift 8-speed right twist shifter INTER 8, compatible with Shimano, optical gear indicator

The Microshift 8-speed right twist shifter INTER 8 is a mechanical grip shifter designed for 8-speed rear drivetrains and compatibility with Shimano-style indexed systems. It uses cable actuation to move the rear derailleur through eight precise gear positions and includes an optical gear indicator mounted on the body for quick visual confirmation of the selected cog. The shifter is intended for standard derailleur setups on city, trekking and commuter bicycles that require a reliable, easy-to-operate right-side shifting control.

Advantages

This right-side twist shifter provides indexed shifting accuracy for eight speeds while maintaining a simple mechanical cable interface that is widely serviceable. The optical gear indicator offers a clear visual reference of the current gear, helping to reduce mis-shifts. The grip-style design allows intuitive thumb or twist operation and integrates with standard brake/shift cable routing used on many urban and touring bikes.

Suitable for

• City bikes with 8-speed rear cassettes
• Trekking and touring bicycles using standard rear derailleurs
• Commuter bikes that require a reliable, easy-to-maintain right-side shifter
• Replacement or upgrade of existing 8-speed grip shifters compatible with Shimano indexing

Key specifications

• Compatibility: 8-speed indexed rear drivetrains compatible with Shimano indexing
• Actuation: Mechanical cable-operated indexed shifting
• Control type: Right-side twist/grip shifter
• Indicator: Optical gear position indicator integrated on unit
• Intended use: City, trekking, commuter bicycles with standard derailleur systems

How to use

Install the shifter on the right handlebar following standard grip-shifter mounting practice, secure the cable to the rear derailleur, and adjust cable tension and indexing at the derailleur to ensure precise engagement across all eight gears. Use a twisting motion of the grip to move up and down the cassette while pedaling as appropriate; the optical indicator shows the selected gear position. Periodically check cable tension, housing condition and indicator alignment as part of routine drivetrain maintenance.

Usage recommendations

For best performance, pair the shifter with an 8-speed cassette and a compatible rear derailleur, keep cables and housing clean and lubricated, and perform final indexing adjustments at the derailleur so shifts are accurate across the entire range.
