Leonardi Gecko Boost Direct Mount Ring

This ring uses a 3-bolt direct mount interface. Before purchasing, confirm that your crankset is compatible with this specific 3-bolt mounting standard, as it will not fit cranksets designed for other mounting patterns like SRAM's 3-bolt or Shimano's direct mount.

The 3 mm offset is designed for 'Boost' spacing, which pushes the chainring slightly outward to accommodate wider rear axle spacing. This ensures your chainline remains straight, reducing wear and improving shifting performance on modern Boost-equipped mountain bikes.

The ring features a specialized anti-chain drop tooth profile designed to retain the chain securely on its own. In most trail riding conditions, you will not need an additional chain guide, though aggressive enduro or downhill riders may still prefer extra security.

No, this is a single-speed specific chainring. It is engineered exclusively for 1x drivetrains, and its tooth profile is not compatible with the shifting ramps or pins found on chainrings designed for front derailleurs.

It is optimized for standard 10, 11, and 12-speed mountain bike chains. If you are running a specific drivetrain ecosystem, ensure your chain width is compatible with the narrow-wide tooth profile for the best engagement.
