Rear Derailleur Microshift MSH-RD-M26L, 7-8 speed (2/3x7/8), long cage, compatible with Shimano, max cog 28–36T, min cog 11–12T, total capacity 45T

Rear derailleur Microshift MSH-RD-M26L is designed for 7–8 speed drivetrains and configured to work with 2x or 3x chainring setups. The long-cage design increases chain wrap and accommodates a wide gear range with a total capacity of 45T, supporting large sprockets in the 28–36T range and small sprockets in the 11–12T range. Compatibility with Shimano-style shift systems makes this derailleur suitable for hybrid, touring and mountain bikes that require reliable indexing and smooth shifting across a broad cassette spread.

Advantages

The long-cage construction provides extended chain capacity and improved chain tension on large cassettes, reducing chain drop and improving chain management on steep terrain or loaded touring setups. Compatibility with Shimano-compatible shifters enables straightforward installation and predictable indexed shifting. The unit’s specification for 7–8 speeds and wide sprocket support makes it possible to use larger rear cogs for easier climbing without sacrificing higher gear options.

Suitable for

• Hybrid and commuter bicycles needing a wider gear range
• Touring bikes carrying luggage and requiring greater chain capacity
• Mountain bikes using 7–8 speed drivetrains with larger rear sprockets
• Bikes configured with double or triple front chainrings (2x/3x)

Key specifications

• Speed compatibility: 7–8 speed drivetrains
• Configuration: suited for 2x or 3x front chainring setups
• Cage length: long cage for increased chain wrap and capacity
• Total capacity: 45 teeth
• Maximum rear sprocket supported: 28–36 teeth
• Minimum rear sprocket supported: 11–12 teeth
• Shift system compatibility: Shimano-compatible indexing

How to use

Install the derailleur on the bike’s derailleur hanger following the manufacturer torque recommendations for the mounting bolt and attach the chain and cable according to standard indexed derailleur setup procedures. Adjust high and low limit screws to align the jockey cage with the smallest and largest sprockets, then set cable tension to achieve accurate indexing across all 7–8 speeds. Ensure the B-tension is adjusted so the upper jockey wheel clears the largest sprocket within recommended distance for quiet, reliable shifting.

Usage recommendations

Use the derailleur with Shimano-compatible 7–8 speed shifters and maintain regular cable and housing inspections; lubricate pivot points and keep the drivetrain clean to preserve shifting precision. When using the largest supported sprockets (up to 36T), verify chain length and B-tension settings to avoid overshift or chain sag. For loaded touring or off-road use, check limit screw settings and cable stretch before long rides.
