Campag cassette ?

[gbb]

Thats wierd....
Playing with the gears yesterday and i noticed the 12T on my Mirage cassette has what appears to be 'bent' teeth. Slowly turn the cassette when looking at it from behind and the teeth appear bent. The teeth are'nt going through a vertical plane if that makes sense.
So i took the 12T of my previous cassette with the intention of fitting that...and it shows the same bent appearance .
Have i been tightening the cassettes too tight and warping the last sprocket ? or maybe they're meant to be like that ?
The bent tooth is most noticeable where the sprockets machined out for shifting so maybe its meant to be that way, but it looks odd.

Can anyone look for me ? see if theirs is the same....even better if you've an old cassette to have a butchers...

dont know about Campag, but Shimano ones are like that

Teeth on cassettes have some strange shaping to help gear changes. They look very strange when you inspect them closely, but they seem to work!

Don't worry. They all do that, Sir.

On an old Chorus cassette it has '10s 12 A O' and a delta symbol stamped under some consecutive teeth on the 12 sprocket . The O tooth is in a different vertical plane to the A, and they're both shaped differently too.

The teeth have varying side filings on them to aid shifting as well as chipped edges on the12 and A - as the others have said it's perfectly normal.
