Making up a campagnolo cassette

Jabbertaff

I have numerous campagnolo Chorus and centaur cassettes, I normally run a 13/29 cassette but following a winter on my cube with 105 12/28 cassette I would like to fit a 12 to the campagnolo cassette, it seemed the only gear to drop out was the 16, so I've taken that out and added the 12, I've run the bike up on the bike stand and the gear changing is very erratic in the middle of the cassette can any one shed some light on why this is so? I've red some where it could be a timing issue,
Am I just trying to have too much spread of gear?
Does any one else use a 12/29?

I run Centaur with a 12-29 Miche cassette on one bike... no problems at all.

If you look at any cassette, all the sprocket teeth are aligned to ensure smooth shifting - by missing a sprocket, the teeth are no longer aligned and therefore shifting will be rough. Also, make sure the spacing is the same - the spacers on some Campagnolo cassettes are sprocket-specific. I'd just buy a replacement cassette.

That's the problem, apart from a Miche cassette which I'm not sure about, Campagnolo don't make a 12-29, so after spending hours trying to make up two cassettes I've just going to stick to what I already use :roll:

I'll just have to make sure the tool kits in the van for 3 day event.

I have a 12-29 Chorus on mine, Jabbertaff.
