Shifter Microshift INTER 3, right-side 3-speed twist shifter compatible with Shimano, optical gear indicator

Microshift INTER 3 is a right-side twist shifter designed for 3-speed drivetrains and made to be compatible with Shimano systems. The unit uses a twist-grip actuation and includes an optical gear indicator for fast visual confirmation of gear position. Engineered for simple, reliable shifting, this shifter fits bikes that require an intuitive control interface and straightforward mechanical integration with common Shimano-compatible hub and derailleur setups.

Advantages

The twist-grip design provides smooth, single-hand shifting and reduces the chance of accidental gear changes. The optical gear indicator gives an immediate visual reference to current gear selection without the need to pedal or inspect the drivetrain closely. Built with an ergonomic grip profile and a compact housing, the shifter balances comfort and space efficiency on the handlebars while maintaining mechanical compatibility with typical 3-speed systems.

Suitable for

• City bikes and urban commuters that use 3-speed hub or derailleur systems
• Trekking and leisure bicycles where simple, reliable shifting is preferred
• Bikes with Shimano-compatible drivetrains requiring a right-side twist shifter

Key specifications

• Mounting position: right-side handlebar
• Number of speeds: 3
• Actuation type: twist-grip (rotating grip)
• Gear display: optical indicator for gear position
• Compatibility: designed for Shimano-compatible 3-speed systems

How to use

Install the shifter on the right side of the handlebar and route the shift cable to the compatible hub or derailleur following standard cable routing practices. Rotate the grip forward or backward to select the desired gear; the optical indicator will show the current gear position. After installation, adjust cable tension and indexing as required to ensure precise engagement across all three gears. Routine checks of cable condition and proper lubrication help maintain smooth operation.

Usage recommendations

For reliable long-term performance, use quality shift cables and end caps, inspect the optical indicator window for dirt or damage, and perform periodic cable tension adjustments. When pairing with a Shimano-compatible hub or derailleur, confirm cable pull and indexing compatibility during setup to avoid mis-shifts.
