Or maybe not! My Professional SLX was raced with the DuraAce 7400 that's still on there and the owner did quite well. Certainly better than I can push it at this point. My Titanio has also never spontaneously combusted, but I'll keep a pail of water nearby just in case. Now, my wife's Primato/to-be-determined will never know the indignity of such character asassination, as I am ordering Campy 2009 Centaur bits for it this afternoon. Especially after seeing OFG's incredible Primato. Oh, and I won't even go into all of that horrid Shimano nonsense on my Master Extra Light.
