On my Roadeo I use a Titanium White Industries 108mm with a 46/30 Rene Herse 9-12 speed crankset. I use a Dura Ace 7700 front Der On my Norther Lyon I use the fancy high end IRD/Sugino ball and cup BB with a 107mm spindle and an older Rene Herse 44/28 crankset. I use a CX70 front derailleur On my custom Falconer with a 120mm OLD in back I use a Phil Wood 103mm BB with a Rene Herse 9-12 speed crankset and 42/26 rings with a CX70 front Der.
All three of these bikes have Dura Ace 7700 down tube shifters.
