I have a friend building a bike with all Campagnolo 8 speed but has an 8 speed Shimano wheelset. Is there a cassette that fits shimano hub and will work with Campagnolo drive train?

Help is much appreciated in advance.

Really? The google search took .51 seconds...

I'm sure someone who has done this will be able to provide more information, but here is my take on it...

Rule number 1, Capagnolo 8 speed cassettes are wider than Shimano 8 speed cassettes, so you need to make sure that Campagnolo spacing will fit on the Shimano 8 speed freehub.
Sheldon Brown's cassette cribsheet.
https://www.sheldonbrown.com/cribsheet-spacing.html

Shimano 8 speed freehubs were usually Uniglide/Hyperglide and limited to 8 speed and not 8-10 speed. An Ultegra 6402 freehub is an example of an 8 speed freehub.

If the freehub body is an 8-10 you can run 8 speeds with Campagnolo spacing. It is is not, you can run 7 of 8 speeds, at the Campagnolo spacing.

There may be manufacturers that make 8 speed Campagnolo spaced cassettes that will fit a Shimano freehub. If not, you can get a non-spidered/carrier 8 speed Shimano (SRAM, Sunrace, etc) cassette and take it apart and use 3.1mm 7 speed spacers between the cogs. I've never re-spaced a cassette to Campagnolo spacing, but I've re-spaced enough to work with different speed shifter cable pull to know it is pretty easy.

Spending 10.51 seconds would have told you the compatibility is Campagnolo. He is using a Shimano freehub.

It's a Miche Primato cassette, known far and wide (I guess not wide enough) to offer Campy spacing for Shimano hubs. The 'component compatibility' refers to the shifters/derailleurs it will work with. You can trust me on this one, I've installed lots of them.

I did see this one and before I've posted the question here i spent a good 7200 seconds looking for a compatible cassette but also one that isn't overseas.

bikeinn states the miche is compatible with Shimano HG hubs only. Wont work.

cxwrench

What hub is on this rear wheel?

malcala622

Im baffled but he wants to put an 8 speed cassette on a 11 speed fulcrum carbon hub. I doubt the hub is HG.

A Shimano cassette was removed.

Fulcrum makes Shimano compatible wheelsets. I have 2 of them.

Well, I apologize. Good find and remarkably quick.

Look up Jtek Shiftmate. The Shiftmate 1 lets you use an 8-speed Campy shifter and rear derailleur with an 8-speed Shimano cassette.

cxwrench

Or this. Always been impressed w/ how well these things work.

malcala622

I read up on that jtek shiftmate 1 and currently all Ive found are sellers from overseas.

I'll hold out for a reply with a cassette recommendation.

Thanks everyone so far

HillRider

Actually Shiftmates are currently made in the UK so that's why sellers are overseas. I've used appropriate Shiftmates to match Campy and Shimano 9 and 10-speed components and they work wonderfully well.
I'd go with the Shiftmate as everything else is pretty much a kludge.

FastJake

Shiftmates are a kludge.

Just get a 7-speed Shimano cassette and toss an extra cog on the back/front. According to Sheldon's cassette spacing table, it's the same 5.0mm cog spacing as a Campy 8-speed. 7-speed Shimano cassettes are cheap and readily available, or at least they were the last time I bought them...

what’s the fear of “overseas”?

malcala622

I never said theres fear of overseas. To begin with its not my personal build so to recommend ordering from overseas might not be a route my friend would want to take. And 2 the wait time is uncertain.

Its easiest to see if there's a cassette that can be used without having to order extra parts.

John, this part of your reply is incorrect.
All Shimano road 8 speed freehubs will accept a 6-7-8-9-10 speed cassette. 6 and 7 require spacers behind the cassette, of course, but 8-9-10 speed Shimano compatible cassettes are all the same width.
At this very moment, I have 6402 and 7403 hubbed wheelsets running 6, 8, 9 & 10 speed cassettes on different bikes.

70sSanO

That’s fine. A while back I put my 6402 UG/HG freehub against my 7700 freehub body and the splined section appears to be shorter on the 6402. I thought I tried a 9 speed cassette but I don’t remember. I was doing a lot of mix-n-match with freehub bodies. I need to take out my digital calipers and actually measure the spline area of each one someday.

Thanks!

John

Edit Added: I do know that a 7403 will take a 10 speed cassette because I remember when miamijim stuffed a 7403 with a 10 speed cassette into a 126mm old.

🙄 why don’t you simply ask your friend if he’s OK with ordering from overseas, instead of taking it upon yourself to limit his options? Aren’t you going to have to order a cassette in any case? Almost every in-stock item I have ordered from the UK has come in 4-5 days

malcala622

It's easier to ask here if there's a cassette that will work without the extra jtek component. Its an easier option and cost saving if only one component purchase is needed instead of 2.

If every cassette is ruled out then yes ill recommend the jtek.

im looking at every option out there to best help him before any purchases are made

A Fulcrum wheel which accepts an 11 speed Shimano cassette can easily be adapted to 8 speed Campagnolo spacing. All you need is an 8 speed cassette with all loose cogs and thicker spacers to adapt it to the wider Campagnolo spacing. You would need spacers 3.2 mm thick to convert to Campagnolo 8 speed spacing.
Any 11 speed Shimano compatible freehub is HG compatible

I wanted to post to this thread and agree that I was wrong to state an 8 speed UG/HG freehub body would not fit a 9/10 speed cassette.

I dug out 9 speed and 10 speed cassettes and tried them on a 6402 freehub body and they do fit.

I don't want to have anyone read this thread and think they wouldn't fit; not that anyone now, or years from now, would have a reason to believe, or care, what I say.
