Sorry if this has been covered already, but I'm currently trying to fit a pair of TA Pro 5 vis to my Eisentraut, and these really don't want to play well with modern BBs where the spindle is symmetrical between the DS and non-DS. The non-drive side arm is sticking out too far, while the driveside is a little too close to the chainstay. This is on a 115mm JIS spindle. I've found threads on BF and elsewhere regarding spindle type (JIS, proprietary, etc) as well as recommended length (people say ca. 118mm), but nothing really on recommended solutions for bottom brackets. Is everyone here using vintage Stronglight BBs with asymmetric spindles, and, if so, is it possible to pinpoint a specific model or length that works best? Are there any modern sealed BBs that work here?
