Cassette Microshift MEZZO R8 8-speed steel 11-34 teeth compatible with Shimano nickel

Microshift MEZZO R8 8-speed cassette in steel with a nickel finish provides an 11–34 tooth sprocket range (11-13-15-18-21-24-28-34) compatible with Shimano 8-speed drivetrains. Constructed from stamped and heat-treated steel sprockets, this cassette is intended for road and touring bicycles that require a broad gear range for varied terrain. The nickel coating helps resist corrosion while maintaining consistent engagement with chain and derailleur systems. Installation is designed for standard 8-speed freehub bodies and the cassette delivers predictable, index-friendly shifting with common 8-speed chains and derailleurs.

Advantages

The steel sprockets offer high durability and wear resistance compared with softer materials, making the cassette suitable for long-term use under load. The 11–34 tooth spread provides low climbing gears and close low-end steps for easier cadence management on hills, while the nickel finish reduces surface corrosion and maintains smooth tooth profiles for reliable chain engagement. Compatibility with Shimano 8-speed systems simplifies upgrades and replacements without requiring changes to existing shifters or chains.

Suitable for

• Road bikes used for long rides and mixed terrain
• Touring bicycles carrying luggage and varying gradients
• Commuter bikes requiring a wide gear range for urban and hilly routes
• Riders replacing worn 8-speed cassettes with a durable steel option

Key specifications

How to use

Fit the cassette onto a compatible standard 8-speed freehub body following manufacturer torque specifications for the lockring. Ensure the freehub and hub threads are clean and lightly greased where appropriate before installation. Use a correct chain length and verify derailleur limit screws and indexing are adjusted for smooth gear changes across the full 11–34 range. Periodically inspect sprockets and chain for wear and replace the chain as needed to prolong cassette life.

Usage recommendations

For optimal performance, pair this 8-speed cassette with a matching 8-speed chain and Shimano-compatible derailleur. Regular cleaning and lubrication will extend service life; replace the chain when stretching to prevent accelerated sprocket wear. When installing, confirm lockring torque and ensure the hub/freehub are free of debris.
