We have a huge range of bike chainsets at Sigma Sports for road, gravel and mountain bikes. As core components of your bike's groupset, chainsets transmit the power from your legs through the cranks and chain to the rear wheel. MTB chainsets come in various configurations, from single ring setups with thick/thin profiles to double and triple ring cranksets, while road bike chainsets have larger chainrings. Learn more about cranksets in our guide.
