The Park Tool LRT-3 is a precision-engineered service tool designed for professional mechanics and dedicated home enthusiasts working on Specialized, Cannondale, and FSA modular cranksets. It allows for the safe installation and removal of direct mount chainring lockrings, ensuring your drivetrain remains secure and properly tensioned. While it provides unmatched accuracy when paired with a torque wrench, users should note it requires a specific 36mm hex drive interface and is not intended for standard cassette lockrings.

No, the LRT-3 is specifically designed for direct mount crank chainring lockrings and does not fit standard cassette lockrings.
While it can be used with a large adjustable wrench in a pinch, using a torque wrench is highly recommended to meet manufacturer torque specifications.
It is constructed from 4140 heat-treated steel for maximum durability and strength.
The LRT-3 fits modular crank systems from Specialized, Cannondale, and FSA.
It allows you to attach the tool to a torque wrench using a 36mm crow foot, enabling precise tightening of the lockring.
Ensure the tool is pushed fully into the notches and hold it steady with one hand while applying pressure with the other.
Clean the lockring thoroughly with a degreaser and a stiff brush to ensure the tool can seat properly.
To use the LRT-3, ensure the lockring notches are free of debris or grit. Align the tool teeth fully into the notches before applying pressure. When using a torque wrench, remember to account for the additional length of the crow foot in your torque calculation if using a standard extension.
To maintain the tool, simply wipe it down with a clean, dry rag after use to remove any grease or chain lube buildup. Store it in a dry tool drawer or on a pegboard to avoid contact with corrosive materials. Do not use an impact wrench with this tool, as the shock can damage the tool's teeth or the aluminum lockring interface.
