Cassette Microshift MEZZO 7-speed steel compatible with Shimano 12-13-15-18-21-24-28 nickel

Microshift MEZZO 7-speed cassette in steel with a nickel finish, compatible with Shimano freehubs, provides a 12-13-15-18-21-24-28T sprocket range. Designed as a replacement cassette for city, touring and recreational bicycles, it delivers the standard stepped 7-speed progression for reliable chain engagement and straightforward shifting across varied terrain. The steel construction and nickel finish prioritise durability and corrosion resistance while maintaining predictable drivetrain behaviour on typical commuter and leisure bikes.

Advantages

The steel sprockets and nickel plating offer long-term wear resistance and improved protection against rust compared with untreated steel. Compatibility with Shimano-style freehubs ensures fitment on a wide range of wheelsets without modification. The conventional 12-28T spread balances low-end climbing assistance and higher top gears for flat sections, giving versatile gear ratios suitable for mixed urban and touring use. The cassette is serviceable as a direct replacement, enabling straightforward maintenance and restoration of drivetrain performance.

Suitable for (tasks / use cases)

• City and commuter bicycles requiring a durable replacement cassette
• Touring and leisure rides where a 7-speed gear range is preferred
• Recreational bikes and older frames with 7-speed drivetrains
• Workshops and home mechanics performing routine drivetrain maintenance

Key specifications

• Sprocket tooth range: 12-13-15-18-21-24-28T
• Material: steel sprockets with nickel finish
• Compatibility: Shimano-style freehub bodies (7-speed spacing)
• Intended use: city, touring, recreational cycling

How to use

Install the cassette onto a compatible Shimano-style freehub body using the appropriate lockring and a cassette tool. Ensure the freehub and hub threads are clean and lightly greased where specified by the wheel manufacturer. After installation, check rear derailleur indexing and adjust limit screws and cable tension as needed to achieve smooth shifting across all seven gears. Perform routine inspections for wear, lubrication of the chain, and correct chain length to maintain shifting performance and prolong cassette life.

Usage recommendations

Use with a properly sized chain for 7-speed systems and maintain regular chain replacement intervals to reduce premature sprocket wear. Avoid aggressive cross-chaining and inspect the cassette for wear or damage if shifting becomes imprecise.
