Chainrings
A drive is efficient when the chain and chainring work together perfectly. The most important factor here is an optimum form and force fit, which is achieved by minimizing play between the drive components. Precision is central to KMC in the development of advanced drive components. For example, narrow-wide is a new type of tooth profile. The chainrings have alternating narrow and wider teeth that perfectly fill the space between the plates, making the system less prone to chain throw-off.
