• Rotor BSA30 uses outboard bearings so the spindle length of the BB30 crank would be too short .. shell width of BB30 (road) is 68mm with internal bearings .. I thought along similar lines for a past project. There was a dodge that I saw someone used on the Weight Weenies board once of using a Cannondale crank with a mountain spindle and some custom machined cups with thin bearings.
