Hi;
I'm in the process of rebuilding my De Rosa (after it gets back from paint) as an all campy record bike. So needless to say like most projects I have some parts and am looking for others. My question is regarding campy rear derailuers. I will be using downtube shifters with an 8 speed hub, how far back on campy models can I go..... or which models will have the correct travel length for an 8 speed hub. Can a Super Record work or do I need something newer?

Thanks
