The box said 72 pieces. After I installed them I was One Short. Why wouldn't they include One extra incase of a problem. Nothing is exact and this proves that. I had to cut down the ones for the back because they are shorter spokes. I used pieces to cover the last spoke. Hope they stay on the bike. The ones I did receive were nice and tight and click when installing them. They don't go on sloppy so I gave the install 4 stars. I did work more on this set. I have used spoke skins on other bikes.
