Chain rings are an often overlooked component. But think about it - the drivechain wraps around the chainring every revolution of every pedal stroke propelling you forward. A poor interface here can result in a significant reduction in efficiency, lost power transfer and even a skipping or snapped chain. Good quality chainrings mesh well with the right chain and form a durable, solid platform transferring all your energy into forward motion. There's often no need to replace the whole crankset, unless you want to try different length crank arms. Fitting a set of quality new chainrings is a fantastic and low-cost way of keeping your drivetrain at peak performance. Just choose the right Bolt Circle Diameter (BCD) and how many teeth you require, then spin in bliss!
