Except for kids' bicycles the drivetrain is everything in any bike. On it depends the energy transfer from our legs to the crank, chain and the rest of the gears.
The main rule for the drivetrain to work correctly is to avoid mud and dust, as well as applying suitable lubrication to improve its function and avoid excessive wear.
The key part of any drivetrain is the chain, which delivers the energy and obeys the orders of the gear levers when these command a change to another sprocket or chainrings via cables and covers .
According to the cassette and the number of sprockets, your development would be completed with 3, 2 or 1 sprockets. By cassette we mean the set of sprockets that are fixed to the hub of the rear Wheel, which together with the chainrings and chain form the drivetrain. Also, you need to know that the cassette, as well as the sprockets, can have a different number of teeth depending on the range or modality that will make their development more or less suitable depending on the type of bicycle we want.
Obviously, mainly in the city segment, you can also choose a fixed sprocket or a Single Speed (just one free sprocket). Precisely for city cyclists, don't forget that you can add a bash guard in order to avoid getting your trousers or shoes dirty.
For those looking for the latest in cycling technology, Motocard has Electrical groups for the drivetrain, that is: cableless and via a digital signal issued from the levers to the derailleur and gears. All this via a small, lightweight battery with a long autonomy and easily recharged.
Finally, don't forget that the drivetrain of the bicycle comes from the force you apply to the pedals and cranks. To best transfer the energy and gain confidence on the downhill, we recommend that you use automatic pedals which, linked to the cleats of the shoes, ensure an optimum and secure hold of the foot on the pedal.
