What are common causes of chain suddenly falling in from big ring to small when shifting down the casette (harder gear)?
This is on Rival 11 speed. Chain is between 0.5 and 0.75 wear. Drivetrain is currently somewhat dirty, but not excessively so. Plan to deep clean and renew chain at weekend, but wonder if anything else is causing it...
