DD, it is about time you started tuning/rebuilding your wheels. The bikes that you post are testament to the top shelf handiwork you are capable of. With out the weave, that broken spoke will flop around. But you probably wont break one. I suggest that you put that wheelset on your Casati and use new rims, spokes and nipples on Record hubs to build wheels for your Bianchi. Then you can go back and play with that 4X wheelset.
