Bicycle Mechanics - Campy Cassette & Shimano Hub

I have a Campy shifters, derraileur and cassette, but the hub on my rear wheel is Ultegra. I need an advice as to what is the most economical way to get the cassette fitted on the wheel. Thanks.

Wheels manufacturing offers kits to make a shimano 8 cassette work with Campy 9 shifter/der and a kit to make shimano 8 cass. work with Campy 8shifters/der.
They also make a 10sp cassette to fit and 9sp to work with their respective shifters. I've read that a 9sp Shimano Cassette will work fine with campy 9sp drivertrain. American classic also makes a 10sp cassette to fit on shimano hub.

Cycle Dynamics in BC Canada also makes Campy/Shimano compatible cassettes in Ti. if you are weight conscious.
Thanks for the advice. Iwas not clear about the problem I am trying to solve. I maybe wrong, but this is the story: I originally had a Shimano setup which included 9 speed casette and lever shifters mounted on Kelly "Take-Offs". I thought that reaching the shift levers was acquard in some positions, so I replaced the brakes/shifters with Veloce 9 speed shifters - I like the way these feel. As soon as I did that, some of the gears were shifting by two, instead of just one cog, no matter what adjustments I tried. So I installed Campy derraileur, which made the situation much worse ( I was still keeping the Shimano cassette). Finally I am trying to install Veloce cassette, without buing a new wheel of a hub, thinking that I'll modify the cassette to fit on the Shimano hub, but it appears too difficult/ impossible. When I set the two 9 speed cassettes side by side, the Veloce is approximately 5mm wider (as are the spacers), so I thought the shifting problem is caused by the now wrong spacing. Unfortunatelly, the Shimano cogs are held together 5 at the time, so I cannot re-space them. I guess what I am seeking are Shimano cogs with Campy spacing, or a way to fit Campy cassette on Shimano hub.

You buy a cassette with Shimano splines and Campy spacing from the companies previously listed.
Yep, branfordbikes carries them, excelsports carries them also. The difference between a 9sp shimano and 9sp campy cassette shoudl not be 5mm though.
Campy 9sp cassettes I know the cogs themselves are a bit thicker, but the difference between the two cassettes should be very minimal. I know there are some on here who have run shimano 9sp cassette with Campy 9sp shifters and derailleur. LIke you found out you can't mix campy shifters and shimano derailleurs though.
I found some of the info shimano use 2.56mm spacer and cog is 1.76mm and campy uses 2.8mm spacers and cog is 1.75mm. Center to Center Campy 9sp cogs are 4.55 and Shimano is 4.34mm. So that would make a diference from cog 1 to cog 9 total of 1.89mm or difference of .21mm per cog.

To use the Wheels Mfg. spacer kit, you will need a lower end Shimano cassette. The 105 and better use a spider assembly for the 5 largest gears, essentially making them one unit. The Sora and lower have some small screws holding them together. Just remove the screws and discard them, replace the spacers with the ones from Wheels Mfg., and you are good to go. I am doing a similar refit so that I can get a Spinergy Xaero-X for the rear of my Mirage equipped Bianchi. I have the front already, but I really want a matching set of wheels, and the splines are different between my Campy 8 and the newer Campy 9/10 hubs, as is the spacing, so I am going to get a Shimano freehub equipped rear wheel and a Shimano cassette, and use the Wheels spacer kit.
This sounds as an economical solution, otherwise the proper cassettes and spacers together cost close to pretty decent wheel.

Yup! One of the shops I go to told me I could get a Mavic cassette to do the job. It was gonna be $120!!! I almost peed myself when they siad that, but caught myself at the last second.

Marchisio is the make you are looking for. They make an economical range of cogs in Campy and Shimnao spline patterns, available individually in any size. They make a range of spacers for each spline pattern, in a range of thicknesses. You can combine these to make any cog-spaceing on any type of freehub.
Torelli is the US importer, but Brandford may be a retailer as well.
Ive used Marchisio on a Campy 8spd, just to obtian larger rear cogs. They work OK, not quite as sweet at the guine article, but quite good enough.
You dont need to fit flashy Ti or expensive kit to solve your problem.
You are correct on the cost of the cassette, if it was a 10sp you could somewhat justify it since cassette is not much more, but on 9sp price difference is quite high. You could pickup a veloce rear hub for around $50 and new spokes for around $20 and not worry about it in the future.

I was considering trying some Campy 9sp shifters a couple of years ago. I called Harris Cyclery to ask if they had the spacers to respace Shimano cassettes to Campy. I was lucky enough to have Sheldon himself answer the phone. When I told him what I was looking for he assured me that the spacing is so close Campy shifters/der will work fine with stock Shimano cassettes. I never did try it, but other posters here have reported success. You might do a search or two as there have been several threads on this over the years.
That may have been the case in the past, but like I said, when laid side-by-side, the Campagnolo cassette is about 5mm wider, than the Shimano. I just put up a proper wheel and Campy cassette, and the combination worked flawlessly in less than one minute of adjusting. I've been riding it for couple of days, no problems. I'll just use this wheel and later get another one for the bike I canibalized it from. Thank you all for your advices, it really helped.
