bicycle chain
Loop driving wheels
A bicycle chain is the loop of linked metal segments that transfers power from the pedals to the rear wheel.
The chain engages with toothed sprockets, converting leg motion into forward movement.
Chains require periodic lubrication and eventually stretch with use: The bicycle chain keeps slipping off the gears.
