There have been several questions about split wheels vs split lock ring wheels. these pictures are all of lock ring wheels. none are the dreaded widowmaker split rims. All of these can still hurt you if mishandled. If I can get pictures of the widowmakers I will add them.

Widow makers now added the last 2 painted red and silver, not the greatest pictures and Cousin didn't have any dismounted so these pictures don't show disassembled wheel
