TOOPRE Mountain Bike Single Chain Guide DH Rear Derailleur Guard 32T-38T Chainring Stabilizer ISCG03/05

The TOOPRE Single-Disc Chain Guide Set is designed for mountain bikes, downhill bikes, and soft-tail frames using a single-chainring drivetrain. It helps keep the chain securely in place, reduces the risk of chain drop during aggressive riding, and provides extra protection for the chainring against impacts from rocks, roots, and rough terrain.

Made with a high-strength aluminum alloy body and durable nylon guide components, this chain guide combines lightweight performance with reliable strength. The CNC-machined structure, anodized finish, and adjustable guide design make it a practical upgrade for MTB riders who demand stable drivetrain performance.

Key Features

High-Strength CNC Aluminum Alloy Body

The main body is made from durable aluminum alloy with CNC machining for precise fitment and improved structural strength. The lightweight design helps reduce unnecessary weight while maintaining excellent durability.

Stable Chain Retention

The upper and lower guide structures help limit chain movement and keep the chain aligned with the chainring, effectively reducing chain drop during bumps, jumps, downhill riding, and rough trails.

Protective Bash Guard Design

The integrated lower protective plate helps block impacts from below and protects the chainring from stones, branches, roots, and trail obstacles.

Wide Compatibility

Compatible with threaded BB bottom brackets, ISCG03, and ISCG05 mounting standards. The included conversion seat allows installation on different frame structures.

Durable Nylon Guide

The chain guide sections use nylon material to reduce friction and noise while offering reliable chain control during riding.
