Electronic groupsets are ever-increasing in popularity and are near-ubiquitous in the pro peloton. The technology has trickled down to lower-tier road and mountain bike groupsets since the arrival of Shimano Di2, and there are now more options available on the market than ever before.

In fact, Shimano (with its Di2 electronic groupsets) and SRAM (eTap) now only offer electronic options for their top-tier road groupsets and there do not seem to be any plans to further develop the brands’ mechanical groupsets.

Campagnolo (EPS) also offers high-end electronic road bike groupsets , while SRAM and Shimano lead the way when it comes to electronic mountain bike drivetrains.

Electronic groupsets offer a number of benefits, including accurate shifting and, in some cases, ease of setup, but some riders prefer the tactile shifting and serviceability of a mechanical groupset. Electronic groupsets are more expensive, too.

In this guide, we’ll take a closer look at what exactly constitutes an electronic groupset, how they work, and the pros and cons of electronic groupsets versus mechanical groupsets. We’ll then outline the major manufacturers, their options and the intricacies between different systems.
