Campy Freehub Issue

elee1

Hello,

I am kinda stuck with my recent purchase. Got myself an Ursus carbon wheel with 3-pawl Campy hub on it. Couldn't run on my bike as the drivetrain on my project is all SRAM Force 22. Took the hub out. Found "CHO-11" and "SEN-08" printed on the bottom of the hub. Searched on ebay and bought a Shimano one with the same writing on it. But once it arrived, I discovered that the size of the base is much bigger comparing to one on the wheel and now I'm stuck.

Here is the pic (campy is on the right, one i have a trouble with): https://www.flickr.com/gp/100865512@N04/mXv6J1


Reached out to Ursus, and they said as the product is discontinued, they won't be able to provide any help. Totally sucks!

The one I bought:

Can anyone help to decipher "CHO-11" and "SEN-08"? I'd guess "11" stands for 11 speed?! What does "08" mean?

What should I be looking for? I would greatly appreciate any suggestions on my next move.

Big thanks in advance for a help to a newbie!!!!

P.S. That's the wheel, by the way (the one with campagnolo freehub).

Miche freehubs have the same finish. It is possible it one of those.

Photos of your freehub and the bearing I'd would be helpful.

Here is a link to the photo of the hubs. The right black one is Campagnolo, substantially smaller than the right Shimano one.

Thanks.

Just fit a Campagnolo 11s cassette on the wheel and it will work fine with the rest of your components - the cog spacing is such a close match that the shifting is essentially exactly the same regardless of which manufacturer's 11s cassette you are using. See, for example, http://fitwerx.com/campagnolo-shimano-and-sram-11-speed-wheel-compatiblity/ and http://www.velonews.com/2013/09/bikes-and-tech/drivetrain-compatibility-hidden-in-plain-sight_303199.

Big thanks for the advise!

It was a backup plan since the beginning. Kept it as a last resort as I was worried about compatibility issues. Got myself the Campy Centaur cassette last week (unexpected expense, but worth it!). All fit well, so far no issues. Will have to work out how to tune the shifting on the thing though.

Once again, thanks for all hints!
