Hi forum,
I know its early days but has anyone yet fitted a Campy freehub yet?
Is it just a standard 17mm axle fitting?
Wanted to make sure before parting with money.
Thanks
If you happen to be running 11 speed, Shimano and Campagnolo spacing are the same for 11 speed and you can use any Shimano compatible cassette with the original freehub (this is not the case for Campagnolo drivetrains that are not 11 speed).
Hi Forum,
I know its early days but has anyone yet fitted a Campy freehub to the new hub?
For 11-speed, I believe the cog spacing is the same between Campy and SRAM/Shimano so you can use any cassette. For other sizes…no idea.
Campy 8 speed and Shimano 7 speed use the same spacing, which can be useful for fixing up very old Campy bikes. The others (aside from 11 speed) all seem to be different enough that it’s hard to achieve good shifting with a durable adjustment. Sometimes it sort of works OK for a while but I’ve seen a lot of mix-and-match bikes and most don’t perform at a level of quality I would recommend.
Thanks for all the reply’s today, guys.
My Bianchi is equipped with a 9-speed cassette and have used it on previous trainers, they have all had 14mm dia axels. The hub has a 17mm axel and it is proving somewhat difficult to locate a suitable freehub that’s compatible.
Shame really because out of the box the hub looks to be a decent piece of kit and may have to be returned.
On the JetBlack website, they list the Campy freehub as “coming soon” and Zwift have told customers that it’s “coming zoon” so some day it will probably be available. If you only care about good shifting in a few gears, you might be able to adjust it to shift OK in say 3-4 gears you care about most. But it’s not going to be happy across the whole range. Something like a Kickr Core is probably a better choice for now.
I am in the same position. Very ready to return it.
Same problem: I want to ride the hub with 10speed Campagnolo but the only answer from service was:
" We are working hard to create a Campagnolo compatible freehub body which will allow your bike to be fully compatible with our trainer.
Currently, we don’t have an estimated date available for when this will be available, keep an eye on our Zwift Forums for updates."
Shame on Zwift !!
They should have worked hard BEFORE going on the market !!
An appropriate Freehub Body must have an axle-diameter of 17mm and a pawls-diameter of 33mm and fit Campagnolo cassettes.
My disappointment is that they didn’t tell buyers in advance that it would not work with Campagnolo 9/10 speed drivetrains. Zwift is not a good source for drivetrain compatibility info. If you bought the Hub I recommend sending it back and getting any trainer that offers the correct freehub body. The only solution for Zwift Hub users is something like the Miche Primato cassette which is available in the Hyperglide format with Campagnolo spacing. Having used those in the past, I wouldn’t recommend them due to relatively low quality. They shift fine though.
Hi Paul,
where can I find souch a Miche HG with Campy-spacing?

I have bought them in the past but I’m having a hard time finding a source that clearly says it’s the right thing. It’s probably best to visit a bicycle service shop that works with Campagnolo equipment and ask them about any options. I see some things online but I’m unsure if they are right for your equipment.
Here’s a similar product manufactured by IRD, but it has 11-34 gearing so it would require a long cage derailleur. You’re better off with a different trainer that offers a Campagnolo freehub.
Hello Paul, thank you for trying so hard. However, the IRD is quite expensive and for me the largest sprocket can have a maximum of 30 teeth. But based on that, I’ll keep looking.
I found this freehub yesterday:
totalcycling(dot)com/de/Campagnolo-N3W-Freehub-Body-17mm-alloy-axle/m-25022.aspx
N3W hubs have the appropriate 33mm pawls, but I don’t think the specification with 17mm axle is correct. Campy specifies 15mm for the N3Ws
I found a JetBlack Freehub for Campagnolo!!
At futurumshop.nl.
www.futurumshop.nl/jetblack-whisperdrive-body-campagnolo-9-10-11-speed.phtml
And because the JetBlack and the Zwift Hub are structurally identical, it should fit.
There’s still one in stock there.
I’m not sure if the whisperdrive freehub will fit the Volt trainer. Ask Jetblack.
Have asked JetBlack - still waiting
I’ve got the answer:
“Unfortunately the WhisperDrive Campagnolo freehub is not compatible with the Volt trainer, only Volt specific freehubs will work with the Volt.”
For DIY technicians:
There is a Wahoo Kickr Core freewheel body for Campagnolo cassettes that fits roughly:
wahoofitness(dot)com/devices/indoor-cycling/parts-components/campagnolo-freehub-buy
But the pawl ring is a bit too big (34.3 mm).
I sanded the ring down a bit all around with a dremel and now it fits the Zwift hub.
Another simple solution would be an adapter ring that reduces the Zwift Hub’s 33mm ratchet ring to 30mm. Then commercially available Campy freewheel bodies would fit.
But that would be a task for the Zwift Hub designers.
