They might be different though since the Harris page lists the 2004. I have the front wheel from a 04 and the rear wheel from a 05. The rear is the survivor of my accident. The 04 front is a donation from Stickerguy from his Pista. I am selling off the bike.
What's odd and this doesn't answer your question (sorry) Ken is that the front hub looks very much like a DuraAce hub sans the black decal/marking - it has the cutout for it even. Supposedly it's a Shimano hub.
The newer ones have a nice high flange shell as well but are not the same hubs - they are fixed/fixed which is really nice. I do suspect they are catridge though as I've looked at it and they're similar from a glance to the bearings on my Phils.
YMMV.
