My partner's Trek has a BB90 bottom bracket which is two loose bearings in a 90mm shell, seated directly in the frame. I have some spare 48/32 Praxis M30 cranks that I want to put on which have a 30mm spindle.
It looks like this doesn't work? 37mm OD/30mm ID/7mm width bearings don't exist/aren't possible? Do I have any options aside from swapping frame/cranks?
maybe bodge in 2 x 61706 on each side? Probably will just buy new cranks though
