Hi, this is maybe a weird question but I'm not a mechanic. When I removed all my chains I found out that the sproket on the trans side is loose on the axle. There is a hole for a screw but there are no screws and I can't see where on the axle it should go ( there are no marks that shows there was a screw tight on the axle). It is the same thing on the rear sproket but I can see a little groove where a screw could go. Do all the sprokets need to have a screw to lock them on the axles or if they are free on purpose by the compagny?
Funny question but I'll learn
