Setup, Compatibility & Care
Installation of the FCM9020C requires a standard Shimano splined bottom bracket tool and a torque wrench to ensure the crank arms are tightened to the manufacturer's specified force. Ensure your frame shell is properly cleaned and faced before installing the compatible bottom bracket. To maintain the chainset, regularly inspect the crank bolts for proper torque and keep the splined interface clean and lightly greased to prevent creaking. This unit is compatible with SM-CRM90 chainrings. Avoid using harsh chemical degreasers that could compromise the anodized finish or any sensitive bearing seals.
