Magene PES PM Replacement Spider Lock Ring

The Magene PES PM Replacement Spider Lock Ring is designed for riders and mechanics who need a replacement lockring to secure the PES power meter spider to the crank arm.

Secures the Spider Assembly: This lockring helps hold the power meter spider firmly in place, supporting proper crank and power meter assembly. It is an important small part for correct PES powermeter installation.

Tool-Compatible Fitting: The lockring is typically tightened using a 16-notch, 44mm external bottom bracket tool, such as the Park Tool BBT-9. Using the correct tool helps avoid damage during fitting.

Recommended Torque Range: For proper installation, the recommended tightening torque is 35 to 40Nm. Correct torque application helps maintain a secure fit and supports reliable power meter performance.

The Magene PES PM Replacement Spider Lock Ring is a useful replacement part for maintaining compatible Magene PES powermeter crank setups.
