If the frame is the heart of your bike, the groupset can best be described as the engine room. Responsible for getting your bike moving, and bringing it to a stop, bike groupsets come in different configurations from a number of different manufacturers.
Simply put, a bicycle groupset includes all the gear shifting and transmission components of a bike, along with the brakes. If you’re looking to upgrade or replace individual parts of your groupset, components are typically available separately too.
Looking to the current crop of groupsets on offer, the three main brands controlling the groupset market are Shimano, SRAM and Campagnolo. As your budget increases, the quality of materials used improves, whilst becoming lighter and more durable. If you’re on a budget, pre-loved listings from private sellers can be a great way to grab a bargain.
