Cranks & Bottom Brackets 203
The crankset is the component of a bicycle drivetrain that, connected to the bottom bracket spindle, converts the reciprocating motion of the rider’s legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel.
The bottom bracket on a bicycle connects the crankset to the bicycle and allows the crankset to rotate freely.
This class will demonstrate best practices for bottom bracket identification of most square taper bottom brackets and installation.
Join the Yellow Bike and our professional bike educators for a detailed survey of bottom brackets, bicycle cranks, and chainrings. This three-hour class will define bottom brackets, cranks, and chainrings and identify their common types and their anatomies; and will include a guided hands-on overhaul and adjustment. Subject bicycles will be provided, but attendees are also encouraged to bring and work on their own bikes.
