So i was looking for info on a replacement chain for my 8speed campagnolo set up when i strangely only realised i'm running a 8 speed dura ace cassette. for some reason i had thought i had a campy rear to match the rest of the record components.

so then i did a bit more searching and found this bit of info on Sheldon Browns website.

Sheldon says
Campagnolo/Shimano 8-speed cassettes have different spacing , so you can't generally get good indexing using a Campagnolo 8-speed wheel with a Shimano shift system or vice versa.



Center-to-center
Spacing Sprocket Thickness Spacer Thickness Total Width

Campagnolo
8-speed 5.0 mm 1.9 mm 3.1 mm
Shimano
8-speed 4.8 mm 1.8 mm 3.0 mm


I'd never noticed a problem before with running the dura ace cassette. should i be trying to get a campy freehub and change over to a campy cassette?

When i first bought the bike i had it serviced and checked over by a very reputable local bike shop and they never mentioned it either.

worth worrying about?
