Rear Derailleur Microshift MSH-RD-M26S, 7–8-speed compatible with Shimano, short cage, max sprocket 28–36T, min sprocket 11–12T, total capacity 39T

Microshift MSH-RD-M26S is a rear derailleur designed for 7–8-speed drivetrains and is compatible with Shimano indexing shifters. The short-cage construction provides a compact profile suitable for commuter, hybrid and entry-level mountain bikes, while supporting a range of sprocket sizes and a total chain capacity of 39T. The mechanism is engineered for straightforward installation and conventional cable-actuated shifting adjustment.

Advantages

The short cage design reduces chain slap and fits frames with limited rear dropout clearance. Compatibility with standard 7–8-speed Shimano indexing allows use with common shifters and drivetrains. Support for a maximum sprocket range from 28T to 36T and minimum sprockets of 11–12T gives flexibility when fitting a variety of cassette sizes. The derailleur’s construction balances durability and ease of maintenance for everyday riding conditions.

Suitable for

• Commuter and city bicycles with 7–8-speed drivetrains
• Hybrid bikes for mixed-surface riding
• Entry-level mountain bikes requiring a compact derailleur
• Replacement or upgrade on systems using Shimano-compatible indexed shifting

How to use

Install the derailleur on a compatible derailleur hanger following standard torque specifications for the hanger bolt. Route and secure the shift cable through the cable fixing bolt, set high and low limit screws to match the smallest and largest sprockets, and adjust B-tension and cable index to achieve precise gear changes. Verify chain length and total capacity (39T) to ensure the derailleur can accommodate your chainring and cassette combination before final adjustment.

Usage recommendations

Use with compatible 7–8-speed Shimano-indexed shifters and verify sprocket range before installation. Regularly check cable tension and limit screw settings, and perform routine lubrication of pivot points for consistent performance.
