GROWN Narrow Wide Chainring | The Reliable Choice for Simple Riding

A lightweight, high-rigidity narrow-wide chainring that supports the comfort of a 1x drivetrain.

Do you want to simplify your shifting? Do you want a cleaner look? A narrow-wide chainring that enhances chain retention is essential for converting to a 1x drivetrain.

The GROWN Narrow Wide Chainring features an alternating tooth width narrow-wide profile, reducing the risk of chain derailment. It's suitable for a wide range of uses, from city riding to gravel rides and sporty custom mini velos.

Made from lightweight and high-rigidity 7000-series aluminum. After shot blasting, it undergoes anodizing, achieving both a refined texture and durability. The black version offers a sharp impression, while the silver, with its slightly matte texture, blends naturally with classic bikes.

In addition to 36T and 42T 110PCD models, a 56T 130PCD model suitable for high-speed cruising on mini velos is also available. You can choose the optimal gear configuration to match your intended use and bike.
