About BICYCLE SKILFUL REAR DERAILLEUR
Bicycle Rear Derailleur Description:
The rear derailleur is a key component of a geared bicycles drivetrain, responsible for shifting the chain across the rear cassette or freewheel. It enables smooth and precise gear changes by guiding the chain onto the selected sprocket when the rider operates the shifter.
