There are a few different versions of their hubs. Some used bigger flanges and were available as Ti or a rough weave carbon. These are pretty rare now, and hard to come by as they were expensive for their time. Quite often they would carry a little Gold badge made from foil/metal. The issues with cracking flanges don't really apply to these versions as they used thicker flanges, but they were heavier in weight due to their beefier construction.
The other versions were much skinnier, and they were mostly sold as carbon. These have been associated with fracture issues around the flanges due to their smaller design. I think the flanges were machined from billet rather than being forged. They would use a yellow decal too. If I remember accurately then the early version 2's still used the rough weave carbon for a while as well. It was this version that gave Nukeproof a bad name for reliability.
I've got a set of the early Ti versions, and they're a lovely thing. I was always surprised that the freewheel bodies were made from steel though.
