Park Tool LRT-2 Shimano STEPS Chainring Lockring Tool
Perform essential drivetrain service on your Shimano STEPS-equipped e-bike with the precision and reliability of the Park Tool LRT-2. As a cornerstone of our Transmission Tools collection, this professional-grade tool is engineered for the specific demands of modern e-bike maintenance. Designed and built to remove and install the lockring that retains front chainrings found on Shimano® STEPS® e-bike motors, the LRT-2 is an indispensable asset for any professional workshop or serious home mechanic´s toolkit.
Experience the confidence that comes from using a tool that fits perfectly every time. The LRT-2 is meticulously machined to engage securely with the 16-notch lockrings used on popular Shimano STEPS systems, eliminating the risk of slipping, which can cause costly damage to the lockring or the motor itself. One of its most critical benefits is its compatibility with a torque wrench. The 36mm hex drive allows you to use a tool like the Park Tool TWB-36 Crow Foot and a torque wrench, ensuring you can tighten the lockring to the exact manufacturer´s specifications. This crucial step prevents the chainring from coming loose during a ride and protects the sensitive Bottom Bracket and motor components from damage caused by over-tightening.
Constructed for a lifetime of rigorous use, the LRT-2 is forged from 4140 heat-treated steel and plated for exceptional durability and corrosion resistance. This robust build ensures the tool will not flex, deform, or fail under the high torque required for e-bike service, making it a worthy replacement for the Shimano TL-FC39 tool and a reliable investment for anyone committed to proper bike care.
