Setup, Compatibility & Care
Installation requires a standard external bottom bracket compatible with 24mm spindles. Ensure the correct spacers are utilized for your frame's specific shell width (typically 68mm or 73mm) to ensure the spindle sits correctly within the bearings. Use a torque wrench on the crank arm bolt, adhering strictly to the manufacturer's specified torque settings to prevent loosening or spindle damage. For chain line setup, use the provided hardware to align the ring according to your frame's Boost or Standard specification. Regular maintenance involves cleaning the spindle interface and applying a fresh layer of waterproof grease during seasonal service to prevent seizing and ensure smooth rotation.
