Drivetrain refers to the whole system responsible for creating the motion that powers your bike forward. It's essentially a synergy of two rotating gear sets, coupled together with a chain or belt drive. Converting every ounce of your pedalling motion into kinetic energy is a precise business, and modern drivetrain components are some of the most technologically advanced anywhere on the bike. These days choosing a drivetrain setup goes much further than simply the best quality crank set, cassette and chain combination. With a huge variety of gearing options- 3x9, 2x10, 1x11 and internal hub gears being just a few; matching your gear type, ratios and build quality plays a crucial role in equipping your bike for the trail ahead.
