Frequently Asked Questions

1. Question
Does a stronger rear derailleur hanger damage the chainstays during a fall/crash?

Answer
No, modern bikes nowadays have the thru-axles pass through the rear derailleur hanger. The thru-axle provides extremely high rigidity over the entire area; hence, the hanger will not cause the chain stay to break unless the thru-axle breaks. This is extremely rare and would be a major accident, which I hope we will never experience.
