One of the most recent technological advances in the world of cycling, is the use of electronic transmission & gearing. Electronic transmissions use a battery and small motors located inthe derailleur to provide electronic gear shifting, with moving the chain up and down the sprockets.

These gear changes can be customised and programmed, but the main benefit of electronic shifting is the precise gear changes. Shifting using an electronic transmission is also easier, which makes competitive rides quicker, and longer rides out more enjoyable. There are both road and mountain bike specific electronic transmissions, and almost all professional riders have now adopted electronic transmissions on their setup.

Some of the most popular models include the SRAM Rival eTAP AXS, found on many high end gravel bikes and road bikes.
