Rear derailleur Microshift XLE 10-speed, Shimano-compatible, long cage, max sprocket 36–42T, total capacity 47T

The Microshift XLE 10-speed rear derailleur is a Shimano-compatible long-cage unit designed for road and gravel drivetrains. It supports 10-speed cassettes and is intended as a replacement or upgrade for rear shifting systems. With compatibility for maximum sprocket sizes in the 36–42T range and a total capacity of 47T, this derailleur manages wide gear ranges while maintaining chain tension for reliable shifting across varied terrain.

Advantages

The long cage design increases chain wrap and enables the use of larger cassette sprockets, allowing expanded gear ranges without extensive drivetrain modification. Compatibility with Shimano 10-speed indexing ensures smooth shifting performance with many common shifters. The derailleur provides consistent chain tension and helps reduce chain drop on mixed-surface rides. Its construction balances functionality and serviceability for routine maintenance and replacement tasks.

Suitable for

• Replacing a worn or damaged 10-speed rear derailleur on road bikes
• Upgrading gravel bikes to accommodate larger cassettes for climbing
• Retrofit projects using Shimano-compatible 10-speed shifters
• Riders needing a long-cage derailleur to increase total drivetrain capacity

Key specifications

• Speed compatibility: 10-speed drivetrains
• Compatibility: Shimano-style indexing and cable pull
• Cage type: long cage for increased chain wrap
• Maximum sprocket supported: 36–42 teeth
• Total capacity: 47 teeth
• Intended use: road and gravel rear shifting

How to use

Install the derailleur on the rear derailleur hanger following standard torque and alignment practices, ensuring the B-tension and limit screws are set to accommodate the cassette size. Route and tension the cable according to Shimano-compatible indexing conventions, then fine-tune high and low limit screws and indexing to achieve accurate gear changes. Check chain length to match the total capacity of 47T and adjust or replace the chain if necessary. After installation, perform a test ride and make small adjustments to cable tension and B-tension to optimize shift quality across the full cassette range.

Usage recommendations

Use this derailleur with compatible 10-speed shifters and chains. When fitting larger cassettes near the upper limit of 42T, verify hanger alignment and set the B-tension to maintain adequate pulley-to-sprocket clearance. Regularly inspect pulley wheels, pivots, and mounting hardware and keep the assembly clean and lubricated to prolong service life and maintain shifting precision.
