Leonardi Gecko Boost Direct Mount Ring

This chainring uses a standard 3-bolt direct mount interface. You should verify that your crankset is compatible with this specific mounting pattern before purchasing.

The 3mm offset is designed to correct the chainline for Boost-spaced frames. It ensures your chain stays aligned properly with your cassette, which reduces wear and improves shifting performance.

The narrow-wide tooth profile is specifically engineered to retain the chain securely on its own. Most riders will not need a chain guide, even on rough terrain, provided your chain length and derailleur tension are set correctly.

This ring is optimized for modern 1x drivetrains. It works best with 10, 11, and 12-speed chains designed for single-ring setups.

A round ring provides a consistent, predictable feel throughout your entire pedal stroke. It is the preferred choice for riders who want a natural, intuitive power delivery without the mechanical sensation of an oval profile.
