I also happen to have an unused Ultegra 6700 hubset sitting in my bin. I am considering swapping the old hubs for the new. The diameter of the new hubs' flanges(48.5mm front, 53.9 rear) are a little smaller than the old (50mm front and 56.8mm rear according to my calipers).

I don't have a lot of $$ to put into this. Could I reuse the spokes on the new hubs? In other words, are the differences in the hub flanges close enough to reuse the old spokes (which are basically new)?

For what it's worth, it is a 32 hole 3 x pattern. Wheelsmith spokes, brass nipples, Open Pros....
