Leonardi Calibrino Cassette Assembly Tool

The Leonardi Calibrino is designed for standard cassette lockrings. While it fits the vast majority of modern cassettes, it is always best to verify that your specific lockring interface matches the standard spline pattern before use.

Yes, you will still need a chain whip to hold the cassette in place while you use the Calibrino to loosen or tighten the lockring. This tool serves as the interface for the lockring itself, not as a replacement for the chain whip.

Absolutely. It is built with robust materials specifically intended to withstand the repetitive torque and stress of a busy home workshop or frequent drivetrain maintenance.

The Calibrino features a precision-machined interface designed to seat securely into the lockring splines. As long as the tool is fully inserted and held straight during operation, it is engineered to prevent slipping and protect your components from damage.

The main benefit is the precision of the interface. A tighter, more accurate fit reduces the likelihood of the tool camming out or stripping the delicate splines on your lockring, which is a common issue with lower-quality tools.
