Joulvert Crank Set - Playa Models
A Crank Set is the mechanism that attached the pedal to the frame. The crank set is attached to the BB part (Bottom Bracket) and also attached to the pedals.
The Crank Set will arrive in two parts, the right side which include the chain rail, and the left side which is only for the left pedal.
We advise to use a professional bike shop for the replacement as it could get complicated for the unexperienced mechanic. please note that unprofessional un professional assembly can damage the BB part and the main frame.
