pedalaxeln

Pedalaxeln, also known as the pedal crankset or bicycle crankset, is a fundamental component of a bicycle responsible for transferring power from the rider's legs to the drivetrain. It consists of two crank arms, each attached to a pedal, and a spindle that passes through the bicycle's bottom bracket. The crank arms are typically made of metal, such as aluminum or steel, and their length can vary to suit different rider heights and preferences.

The pedals screw into the threaded ends of the crank arms. When the rider pushes down on the pedals, the crank arms rotate the spindle. This rotation is then transmitted to the chainrings, which are mounted on one of the crank arms. The chainrings engage with the bicycle's chain, which in turn drives the rear cassette or freewheel, causing the rear wheel to turn and propel the bicycle forward.

The number of chainrings on a pedalaxeln can vary. Traditional setups often feature one, two, or three chainrings of different sizes, allowing the rider to select appropriate gear ratios for different terrains and riding conditions. The size of the chainrings, in conjunction with the size of the cogs on the rear cassette, determines the overall gear range of the bicycle. Modern bicycle designs are increasingly incorporating integrated cranksets where the crank arms and spindle are a single unit, often made from lighter and stronger materials like carbon fiber. The design and material of the pedalaxeln significantly influence a bicycle's weight, efficiency, and overall performance.
