shimano 7410 crank and BB

erikv · 2006-09-26T21:32:27+00:00

I'm trying to fit my Dura Ace 7410 cranks to a wider BB (they came paired with a 7410 103mm BB). A un53 115mm bb works perfectly in regards to chainline, but the taper doesn't seem quite right. I have been assuming all Shimano square spindle BBs use a JIS taper. Does anyone know if the 7410 has an ISO taper? Or (gasp) perhaps it's own proprietary taper?
