## Summary description

Park Tool LRT-3 is a service kit designed for bicycle maintenance and repair. The kit comes in grey and is supplied as a single pack (1 pc). It is intended for routine servicing tasks and workshop use, providing essential tools and parts in one compact kit for bike mechanics and home enthusiasts.

## Long description

Park Tool LRT-3 — grey bicycle repair service kit is a single-piece service tool designed to remove and install direct-mount lockrings that retain front chainrings on certain modular cranksets. Supplied as a one-piece kit, the tool is built for workshop and home use where accurate lockring control and durability are required. The LRT-3 fits a range of lockring types and works with standard torque-wrench setups to ensure correct installation torque.
Advantages
The LRT-3 is manufactured from heat-treated alloy steel and plated to resist wear and corrosion, offering reliable long-term performance. Its geometry is made to engage both 4-notch and 8-notch lockrings and accommodate 47–48 mm outside diameters, reducing the need for multiple specialty tools. The 36 mm hex drive interface allows use with a crowfoot and torque wrench for measured tightening, improving repeatability and reducing the risk of over- or under-torquing.
Suitable for
Removal and installation of direct-mount front chainring lockrings on compatible cranksets
Workshop maintenance and professional bicycle servicing
Home bike mechanics performing routine crank and chainring work
Torque-controlled installations using a crowfoot adapter and torque wrench
Key specifications
Compatibility: direct-mount lockrings used on specific Specialized®, Cannondale® and FSA® modular cranks
Lockring outside diameter fit: 47–48 mm
Notch engagement: supports both 4-notch and 8-notch lockrings
Drive interface: 36 mm hex for use with crowfoot and torque wrench
Material: 4140 heat-treated steel with protective plating
How to use
Position the LRT-3 tool so its notch engagement features seat into the lockring notches, ensuring correct alignment with either 4 or 8 notch patterns. Attach a Park Tool TWB-36 crowfoot or compatible 36 mm hex crowfoot to the tool and then connect a torque wrench. Use the torque wrench to apply the manufacturer-specified torque when installing the lockring, or to control removal forces when loosening. Inspect engagement during operation to avoid slipping and confirm the tool is fully seated before applying torque.
Usage recommendations
Use with a proper 36 mm crowfoot and torque wrench for accurate torque application. Clean the lockring and surrounding threads before installation. Inspect the tool for wear periodically and replace if notch edges are rounded or plating is compromised to maintain safe, reliable engagement.
