Your boras have the pre-2006 axle that will only accommodate pre-2006 cassette bodies.

Haven't seen those available for quite a while, second hand would be your best bet.
Find an old wheelset or hub for a donor.

you need to change the spindle as well. see this:

Use in conjunction with HU9849 (FH-BO001) on hubs/wheels with non-cutout axles (equivalent of Campy # FH-RE415)

It's a straight swap http://www.bikeman.com/HU9849.html

thanks i will try and find a freehub first if not i will just get a new axel, will the new model axel be ok to use on the wheel?

Not done it personally, but the axle is supposed to be a straight swap for the old one.

Since it's been more than 10 years since the change, you could also look for a "donor" hub for an updated spindle.

Most of the comments above are correct.

You have the first generation (round axle) freehub. You can find any Chorus/record donor hub on Ebay. If the hub is gen2 (3 flat spots on axle), then move both the freehub and the OS axle.

I assume your problem is brearings. Instructions on how to change them is here. http://forums.roadbikereview.com/campag ... 21207.html

Also, see PM

It is an easy swap for the new axle and free hub. I was in the same position and decided to switch rather than look for old parts.

And just think of the 20 grams you'll save

(5 grams on the axle, 15 grams on the cassette body)

why not just replace the bearings if this is the only parts that failed. that's pretty straight forward.
