I need to replace a 7 speed campagnolo rear cassette. Does anybody know if an 8 speed cassette would fit or any other options I have? Cheers.

Are you sure it's a cassette and not a freewheel? I thought Campy freehubs began w/8s, but I've been known to be wrong.

LWaB

vpiuva is correct.

I took it apart and it has 7 spacers and 7 cogs on a splined hub (not sure if this constitutes a cassette but it is not a threaded freewheel). Any idea if I can get replacement cogs?

Photos?

You are correct, it is a cassette. Campy 7 sp cassette hub body is splined exactly the same as an 8 sp. It is approx .4" shorter though. You can use the readily available 8 sp cassettes for replacements. Just loose a cog and spacer. Same lockring will work. Good luck

I was wrong, I've only ever seen or heard of the 8sp cassettes

Is the width difference really that much? .4" = 10.2 mm which seems like way too much for one cog and spacer.

Bullet

Thanks CS1 - that is really useful information for a novice bike mechanic like me. I will have a look and see where I can get hold of an 8 speed cassette (any idea where I can buy one?).

vpiuva

I bought a NOS record one for cheap off ebay ($25?). there's probably more out there to be had.

That's an approx difference. If memory serves me, Campy 7 sp cassettes are spaced at 126mm. Campy 8, 9 and 10 are 130mm, hence about 4mm. Close enough IMO.

Uh, 0.4" and 4 mm aren't quite the same.

Miche do campagnolo 8 speed cogsets.... And since they still make them, the availability is better.

Bullet

Cheers acorn. I think I have found an 8 speed Miche cassette - lets hope it fits when (and if!) I get my hands on it. When I know I will pass on the info.. Cheers
