Looking for advice on swapping hubs. I have a set of wheels that have seen maybe 800kms since they've been rebuilt. They are made up of Campy Nuovo Record hubs, Wheelsmith stainless straight gauge spokes and Alex X2100 Hybrid rims.
I'm planning on reusing the rims and spokes to build onto a Deore XT (HBM737) front hub and Deore LX Parralax (FHM565) rear hub. The hub flanges match and all are 36H.
The wheels are true and in good shape.

This will be my first wheel building project and I'll be using Sheldon Brown's wheelbuilding pages as a guide. I have nothing to lose because at a later date I will be having the Campy hubs professionally rebuilt with same-period rims.

Thanks for any advice.

Have to have all identical rim and hub flange size , to re use spokes.

I expect you will have to buy new spokes of a length appropriate for the next hub/rim combination.

I find it hard to believe that these vintage Campy hubs have all of the same flange and offset dimensions as the more modern Shimano hubs but if you are certain of your measurements, you may be fine. I'm conservative as a wheel builder and never advise reusing spokes but since you say you have 800km on this build, you may get away with it. I just look at it as $50 in the total cost of a wheelset that I don't mind spending for the longevity and peace of mind. YMMV

So I used a spoke length calculator listed by Sheldon Brown's website. For the front it lists a 0.1mm spoke length increase and for the rear a 0.5mm spoke length increase to go from the current build to the new one. Sounds compatible to me.

So...what advice are you looking for?

are the hubs both 126mm spacing? are the flange to locknut measurements the same? I can see where the front has a 50/50 chance of working but the rear?

I've seen comments like this, usually much more value-laden (such as "inferior Campy geometry"), and I'm not surprised. I've measured Super Record, Dura Ace, 600, and 2006 Campy Record hubs, and I just don't see any big differences for the same OLD. The 2006s were 10 speed, but still.

When you take appart the wheels be sure to keep track of the orientation so that the spokes go back the same way. Spokes will last longer than the rims you are building to and can be reused indefinitely.

It's obvious that you don't build with any other hubs than that, because there are PLENTY of modern hubs on the market that will not allow you to use the same length spokes like the OP is trying to.

The labour the OP is going to waste, undoing each nipple and unlacing is ********. Not to mention, it's going to be rebuilt on a very low end rear hub onto an equally low end rim. This project makes no economical sense at all.

Thanks for the positive and constructive advice folks. As for the negative stuff, well... I hope you get something out of it.

Bianchi Girl, the new hubs are a match for the frames they are destined for. Thanks.

Looking forward to this little project.

He's baaaaaaacccckkkkkk!
