I am quite interested to see what it is myself. I haven't done the SP conversion yet but I would have thought the new hub arrangement is much stronger than the old knuckle and c-hub set up. If you are breaking the new hubs aswell then maybe the strength isn't as improved as i thought!
On a little side note, I am currently running the 10 degree c-hubs on my Lazer but does anyone know the equivalent angle on the SP? I am just trying to work out what the characteristic changes will be before I do the switch.
