I just finished my wife's mother's day present and have noticed that the spacing on the Campy Centaur cassette is a bit odd. It shifts into all the cogs, but skips a bit in the 4 and 5 cogs.



It is a little hard to see in the picture, but the spacer between the 4th and 5th gear is noticeably narrower. The space between all the other gears are uniform. When the chain is in either gear, it rubs on the teeth of the other. It also skips annoyingly.

I bought this cassette from pbk a while ago so probably won't be able to exchange it. Plus I would rather not have my wife go without for the time it takes for it to get all the way to pbk and for them to sed a new one.

Is there anywhere where I can get just the spacers? I tried loosescrews and couldn't find anything.
Or better yet, does anyone have a trashed Campy 10 speed cassette that I could buy the spacers from?

Or did I put the spacers on incorrectly? Maybe in the wrong order? FWIW I just pulled the whole cassette, spacers and all, off the plastic holder in the box and just put the whole thing on the hub.

Any other ideas?

THANKS!

Not that it is a correct fix, but it might give you some insight into whether this spacer belongs there or not: Can you swap the spacer from the last cog in its place?

If it shifts correctly up the cluster with the exception of the large cog (it might shift onto it, but not engage correctly), then you might have your answer.

Just thinking out loud.

FIXED!
the spacers were in the wrong order. I just pulled to cassette off the plastic holder it came on, and popped the whole thing onto the hub. Turns out that the spacers are not uniform and go on in a specific order. Why it was packaged out of order, I have no idea. Thankfully they are labeled for size.

I will now go hide in embarrassment.
