The best selection of rear and front bicycle derailleurs and gear shifters from top manufacturers such as Shimano and Merida. Choose a new mountain bike derailleur for better climbs and change gears without any worries! We offer you a wide selection of mountain bike gear shifters (designed to be mounted on bikes with traditional handlebars) and road bike shifters (designed to be mounted on bikes with drop handlebars) for mechanical and electronic shifting. When choosing your road bike or MTB shifters, be sure to match them to your existing transmission. It is not recommended to mix different brands of drive train components, even if they have the same amount of gears.
