The Magene Replacement Spider Lockring keeps a PES power meter spider seated firmly against the crank arm, restoring accurate torque transfer if the original ring loosens or wears out. It tightens with a standard 16-notch bottom bracket tool, making it a straightforward fix for riders maintaining their own power meter setup at home.
