I have a couple different options in front of me.
Have: 172.5 Campy Chorus beautiful condition crank arms (used 42T chainring)
Want: Dura Ace FC-7400 or similar cranks in 170 or 172.5 lenth with chainrings. (Ideal)
or: Shimano 600/105 Crankset with either standard 52/39 or preferably 42T chainring.
(wouldn't be a straight trade for chorus cranks)
OR
Have: Shimano BB-7400 36x24T Italian threaded Bottom Bracket. Spins beautifully.
Want: Campy Chorus 70x102 Italian threaded Bottom Bracket.
I think you see my dilema.
