Can I run Shimano STi shifters and gears with a Campag sprocket??

Can I run Shimano STi shifters and gears with a Campagnolo cassette??

Just wondering,,,,,

No.
Well, yes, sort of, but it's a real pain to get everything indexing, there are lots of compatability issues and it's not a good idea.
So I'd say no.

There are some combinations that work OK. See this article for the full story.

I've heard from guys in the know that Campag and Shimano work pretty well together it's just that the manufacturer doesn't want you to know that. That said I would only try it if I had stuff given to me. I wouldn't got out and buy stuff that I couldn't guarantee will work together. If it's not costing you anything then suck it and see.

yes it does well at least 8 speed stuff works perfectly .
take a look on Sheldon's site
i'm sure he says 9 speed works too.
i used sora 8spd STi with an 8 spd veloce cassette an 8 speed chain with 9 speed veloce rear mech and front mech

No, no, no. 10-speed Campag shifters work (by sheer coincidence) with an otherwise Shimano 8-speed gear train. That's all.

Please don't offer advice unless you know what you are talking about.

calm down Nick. No call to be insulting or so arrogant in giving your views

The combination I commented on is the exact combination that I have been using on my bike for the past two years. It works perfectly.
Try to read the thread thoroughly before posting.

I suggest that you just give your own view or experience without launching a personal attack on another poster however much you may disagree with their views.

Campag and shimano 9 and 10 speed cassette are almost spaced the same. Almost but not quite.

I can't remember the exactly messurement but I think on a 9 speed cassette each sprocket is only 0.2mm (or something like that) different from Shimano to campag. The trouble is that by the time you've moved 9 sprockets you're nearly 2mm out of align and your gears wont change correctly. In theory if you indexed the middle sprocket bang on then you could change up / down all the gears correctly.

In practice your gears will never be perfectly indexed and therefore mixing 9 speed campag/shimano like this will result in lots of ghost shifting. - (Changing up two gears at once / not moving at all/ changing on its own under pressure)

Campag and shimano 10 speed cassettes are even closer. I have mixed and matched these two before now with mixed results. You'll get away with it for an odd ride but it's not a setup that I would recommend. You can expect a few miss-shifts even with new cables.

There are adapters / fudges to get certain setups to work but you're basically best running all shimano or all campag and never mixing the two.

i've run campag 10 speed ergos with shimano 9 speed mechs and cassette by cabling the rear mech as shown here. http://www.hubbub.com/articles_ergopower.html
works perfectly.

Some posters can't even get the same componants to shift faultlessly
Yes you are right of course. Unless you are really broke and stuck with mismatched componentry its best to stick with matched transmission components.

I found that 8 speed Sora STi and campag cassette worked by accident. I put the wrong wheel on my bike without checking and used it for ages before I noticed.

iGaz, I strongly recommend that you do not try to replicate this "perfect" system.

Campagnolo 8-speed spacing is 5.0mm; Shimano 8-speed spacing is 4.8mm. Over 8 sprockets, the accumulated error will be 1.6mm, enough to ensure that some sprockets do not index accurately.

If you don't believe me, try using this excellent website:

The "insult" is in your imagination. My post was a simple statement of fact, and a reasonable request.

If you need any 8 or 9 speed components to match your existing transmission I have a box full of unused 8 and 9 speed Shimano and Campag stuff I no longer need . If you pm me with the details of your existing components I'll see what I have that might help.

Anything is possible. Haven't read through all the posts above properly but any combination not covered by fixes posted above can be sorted with one of these doodads:

Bloody fantastic thing - I'm currently doing the opposite, Shimano rear mech and cassette with Campag shifters (all 10 speed) and it works a treat.

Oh sod it!!! Too much like hassle, have bought a 10spd Veloce groupset and new 10spd chain.

Thanks for the advice though people!
