The pulley sheave assembly is well made and deburred to a high standard. The assembly process of the component is very impressive. The reason I bought this assembly was my old one had damage on the v-grooves. This one had a small nick in one of the V-grooves. Is it usable? Yes. Can this be prevented in the future? Yes. Because I plan to buy another set. A cardboard tube could have possibly prevented this. Unless this was damaged before shipping?
