I had hoped to be able to use DT Swiss but all the suppliers that I can find want me to buy a hub with Shimano free hub and a separate Campag free hub for £45 and swap them over.
That’s cos DT Swiss don’t offer a disc hub with the Campag freehub fitted. It will work, but any dealer will be left over with a Shimano DT Freehub to have to move on.
The flipside is that Shimano DT freehubs seem to fetch good money on ebay for new/nearly new, and Campag freehubs almost fetch nothing in my experience! You might be quids in if you did it yourself that way…
Novatec hubs aren’t that great IMO. Light and work well for a while, but freehubs can fail prematurely and they aren’t anything like as well built/designed as Hope/DT etc. If you’re spending the money on Campag running gear on this bike, I’d not skimp on the hubs myself!
