Real-world use and care

• Pair with compatible sprockets for optimal life and performance; inspect sprocket teeth for wear when installing a new chain.
• Lubricate regularly according to riding conditions and climate; maintain proper tension when the chain is cold to ensure accurate adjustment.
• Monitor chain stretch over time and replace before performance degrades; keep wear in check by aligning the chain with healthy, undamaged sprockets.
