Bicycle Chainrings

More Bicycle Chainrings Info:

The most important compatibility factor when buying a bicycle chainring is making sure it fits your crankset. Many modern chainrings use a direct mount interface, which is specific to the crankset brand and model. Others use a traditional BCD (bolt circle diameter) with a bolt pattern that needs to match your crank arms. Beyond the mounting interface, you’ll also need to match your drivetrain speed and whether you’re running a 1x or 2x configuration. Our product filters make it easy to narrow down exactly what fits your setup.

Round chainrings remain the most popular choice, but oval chainrings have grown significantly in recent years. Brands like absoluteBLACK, ALUGEAR, ROTOR and Wolf Tooth offer oval options that smooth out your pedal stroke and improve efficiency – particularly on climbs and in 1x setups. The difference is subtle for some riders and significant for others. Many who try oval don’t go back.

Material is another consideration. Most bicycle chainrings are aluminum, offering a strong balance of weight, durability and price. For riders chasing maximum weight savings, we also carry carbon fiber chainrings from Carbon-Ti. These are among the lightest options on the market and pair well with high-end road and gravel builds.

Like cassettes and chains, chainrings are a wear item. A worn chainring will cause poor shifting, chain skipping and accelerated chain wear. Replacing your chain regularly is the best way to extend chainring life. When you do need a replacement, getting the right spec first time saves time and hassle- and with the breadth of options we carry, you’ll find exactly what you need here.
