Collection: Groups of top brands bike broadcasts at a better price

THE Bicycle transmission groups They consist of a set of components that allow the bicycle movement, transmitting the power generated by the cyclist to the wheels. The main characteristics of the transmission groups may vary according to the level of performance, use and the type of bicycle. 

Here are some common features that can be found in bicycle transmission groups:

Rear change: The rear gearbox is the component that allows you to select several gears on the rear wheel. High quality transmission groups offer a greater number of gears, allowing greater precision and fluidity in the gearbox.

Change command: The gearbox command is the device that controls the rear gearbox. It can be positioned on the bicycle handlebar, allowing the cyclist to change gears without having to remove hands from the handlebar.

Front gearbox: Some transmission groups also include a front gearbox, which allows you to select several gears on the front wheel. This is particularly common in bicycles with more than one crown in the crankset (front of the pedals).

Front gearbox command: If present, the front gearbox command checks the front gearbox, allowing the cyclist to switch from one crown to another.

Pulpting: The garnish is made up of the pedals and the crowns mounted on the front of the bicycle. The crowns can have different sizes, influencing the transmission relationship and the ease with which you can pedal.

Chain: The chain transmits the power from the movement of the pedals to the wheels. Bicycle chains can vary in terms of quality and wear resistance.

Cassette: The box is a set of pignons mounted on the rear wheel. The box offers a different range of transmission relationships, allowing the cyclist to face different ground conditions.

Change leve: The gear levers are positioned on the handlebar and allow you to operate the gearbox command in order to change gears. They can be integrated with brake controls to offer easy access to both functions.

Brakes: Although they are not part of the transmission group directly, the brakes are an essential component of the bicycles and can be integrated with the change commands. The brakes can be disk or skate, offering different braking performance.
