You mean the cups? Yeah I think most of the old Ti BBs use alloy cups. I think I have a hardcore in my touring bike. I had a pro series but I either sold it or gave it away. I have another hardcore by am missing one cup... I really would love to find one... I have two RH cups for some reason when I bought a box of all the Ti BB parts they had at a used bike shop. I'll have to go hunting when I am down in BC again this summer.
