Without a drivetrain, your mountain bike won’t be going anywhere. If it becomes damaged by time, weathering or an accident, you’ll want to replace the damaged components to prevent other elements breaking, ensuring your MTB stays safe and usable. Decathlon has a full range of MTB drivetrain parts – high quality at affordable prices.

Be sure to look after your drivetrain by cleaning it after rides – particularly wet and muddy ones. Grit, dirt and water can damage the drivetrain in a variety of ways and shorten its lifespan, so keeping it clean is a good idea.

You may want to upgrade your drivetrain in order to increase the number of gears your mountain bike can switch between or change to a one by system. If that’s the case, explore our range of MTB cassettes and gear shifters.
