RFX ChainwheelRole of the chain rollerThe chain wheels are essential to ensure that your chain drive is guided and does not come into contact with other elements such as the lower part of the frame or the air box. When to replace the sprocket? When the sprocket is heavily marked by the chain or no longer turns freely (seized bearing), it should be changed. Useful information:To be safe, measure the diameter of your original sprocket before replacing it. It is best to keep to the standard diameter so that the chain does not touch any parts and does not run out of room.
