Leonardi Gecko Boost Direct Mount Ring

This ring uses a 3-bolt direct mount interface. It is compatible with cranksets that utilize this specific standard, but you should verify your crank's mounting pattern before purchasing.

The 3mm offset is specifically designed for Boost-spaced frames. It ensures your chain line is properly aligned, which helps prevent chain drop and reduces wear on your drivetrain components.

No, this ring is optimized for Boost spacing. Using it on a non-Boost frame will result in an incorrect chain line, which can cause shifting issues and premature wear.

The specialized anti-drop tooth profile is designed to keep the chain secure on its own, even over rough terrain. Most riders will not need an additional chain guide, though it depends on your specific riding style and frame setup.

A round design provides consistent power delivery throughout your entire pedal stroke. It is the standard choice for riders who prefer a predictable, natural feel while pedaling.
