Ensure professional-grade maintenance for your Bosch-powered e-bike with the Park Tool LRT-1 Bosch Gen 2 Bottom Bracket Lockring Tool. This essential workshop-quality tool is specifically designed for the unique requirements of servicing Bosch e-bike drive systems. Precisely machined for a perfect fit, this 8-notch tool removes and installs the lockring that retains front chainrings found on Bosch® Gen 2 e-bike motors after the crank arm is removed. It is the definitive solution for any home mechanic or professional technician looking to perform crucial drivetrain and bottom bracket maintenance with accuracy and confidence.
Precision Engineering for Maximum Protection
The LRT-1 is not just a tool; it´s an investment in protecting your e-bike. Its precision machining guarantees a perfect engagement with the 8-notch lockring, significantly reducing the risk of slipping, which can damage both the expensive lockring and the motor assembly. Work confidently, knowing you are using a tool designed to fit flawlessly and prevent the stripping of delicate components, ensuring the integrity of your bike´s transmission system.
Achieve Factory-Spec Tightening
Proper torque is critical for the safety and performance of your e-bike´s drivetrain. The integrated 3/8” square drive fitting allows for seamless use with any standard torque wrench. This enables you to tighten the bottom bracket lockring to the exact manufacturer specifications, preventing costly damage from over-tightening or dangerous component failure from under-tightening. This feature transforms a potentially tricky job into a straightforward, repeatable, and safe procedure.

As with all Park Tool products, the LRT-1 is built to withstand the rigors of a professional workshop. Constructed from robust 4140 heat-treated steel and finished with a durable plating, this tool resists flex, wear, and corrosion. It is a dependable addition to any toolkit, ready for countless bottom bracket services. This commitment to quality means you are investing in a tool that will perform reliably for years to come.
