Driveside

The driveside refers to the side of a bicycle that contains the drivetrain components. This is typically the right side of the bicycle. The drivetrain includes the pedals, crankset, chainrings, chain, cassette or freewheel, and the rear derailleur. The chain connects the front chainrings to the rear cogs, transferring power from the rider's legs to the rear wheel.

On most bicycles, the rear wheel is attached to the frame in a way that allows the chain to engage with the cassette or freewheel on the driveside. This is why the rear derailleur, which moves the chain across the cogs, is also located on this side. The shifters, located on the handlebars, control the rear derailleur, allowing the rider to change gears.

Understanding the driveside is important for bicycle maintenance and repair. For example, when removing or installing a crankset or cassette, it is crucial to know which side is the driveside to use the correct tools and techniques. Chain wear and lubrication are also primarily focused on the driveside.
