## Overview

The SHIMANO RD-M640 Zee Shadow Plus is a high-performance 10-speed rear derailleur engineered for mountain biking enthusiasts seeking durability, precision, and quiet operation. Featuring Shadow Plus technology to reduce chain bounce and noise, an aluminum body with sealed bearing pulleys for longevity, and compatibility with Dyna-Sys 10-speed systems, it’s designed to elevate your ride with smooth, reliable shifting even on demanding terrain.

## Description

Dyna-Sys specific cable pull for (HG-X) 10 speed mountain drivetrains, improved cable routing, shadow design help eliminate drop out contact. Direct mount frame compatible. Aluminum construction with sealed bearing 11-tooth guide pulley. Shadow plus cage tensioner to help eliminate chain bounce and quiet down the drivetrain.

Review: A lovely addition to a cycle - It's well made, nice and compact and although the specs say that the biggest rear cog it can handle is a 36T it can actually take a larger 42T cog especially on a hardtail bike (due to a lack of suspension induced chain growth). I am running this derailleur on a 14-42T rear gearset. Another thing that can be done, either by use of a spacer or by drilling a hole, is to make this ten speed derailleur work with a 9 speed cassette/freewheel. I currently have it working as a 9 speed derailleur. It's a lovely derailleur and it's compact size makes it ideal for use on small wheeled bikes such as folding bikes. I hope Shimano continues to produce it.

Using the free ride version on my folding bike (11-32) due to the short cage. Shifting performance is great, short and precise. Not cheap but worth it.
