>>1834240I've read in a few places that the only safe bet for this set up is Shimano Dura-Ace (FC-7400).
>>1834241It's a Press fit Bottom bracket assembly, two bearing cartridges are pressed into the shell with a spindle held in place by them, a bastard to remove and slightly less of a bastard to install. these old Klein's had proprietary 75mm BB shells, almost impossible to fity any other type without some serious modification to the shell, either shaving some width off or carving out a 45 degree bevel from the shell edge to accomodate a Mavic 616.
>>1834242See picrel, it's an early to mid 1980's frameset.
