Installation follows standard rear derailleur procedures. Ensure the B‑tension screw is correctly adjusted to accommodate the larger cog range, and refer to Shimano’s technical manual for precise setup steps.
Is the black finish prone to scratching?
The powder‑coated black finish is resistant to minor scratches and corrosion, but like any component, it should be cleaned regularly and protected from harsh chemicals to maintain its appearance.
