Improve the acceleration with our range of right Chainrings. These slip under load and become as piercing as shark teeth. These are employed to connect the crank arm with the assorted chainrings. These are compatible with 3-arm, 4-arm, or 5-arm crank sets. However, based on the type of the cranks, the holes for the pins can be located in assorted locations. These come with a different pitch circle diameter and can also be provided with an alternating width. This results in a much tauter fit and keeps the chain from coming off as easily. They are also called Narrow Wide rings. Based on the rear derailleur being used, these Chainrings are highly serviceable.
