If you're looking for a replacement for your worn-out chainrings or want to replace the original chainring(s) with another model with a more suitable gear ratio, you've come to the right place. Swapping chainrings not only improves the shifting quality and saves weight, but can also spice up the look of the bike. When buying a new chainring, it's essential to pay attention to the bolt circle diameter (BCD) - getting this right is the only way to make sure that the crank fits correctly on the chainring. It's also important to identify whether the chainring is intended for use with a front derailleur or for single chainring '1x' setups. Last but not least, you should make sure that the chainring is designed for the right position in relation to the crank: inner or outer.
