Chainsets & Cranksets

Located at the heart of the bike drivetrain is the crankset, which consists of crank arms and chainrings, and is also known as the chainset.

There are three main formats to choose from – single, double, and triple and this crucial component is what is pedalled to make the bike go forwards. At Chain Reaction you’ll find BMX, road and MTB cranksets in various lengths to suit the bike and the rider.
