When it comes to upgrading your bike’s components, one of the most important decisions you’ll make is choosing the right groupset. A groupset is a collection of bike components, including the brakes, shifters, derailleurs, and crankset, that work together to provide the bike’s drivetrain. Two of the most popular groupsets on the market today are Shimano’s Ultegra RX and GRX. In this article, we’ll take a closer look at both groupsets to help you make an informed decision.
