I am converting a 2018 Trek Superfly, using the bafang bbshd 100mm kit. The length of the spindle is fine, not the diameter. I had an xt crank that I removed, that spindle diameter is 24mm. The bafang spindle diameter is 33.5 - 34mm. I knocked out the pf 89 bottom bracket that was installed. I need help determining the correct bottom bracket to allow for this larger diameter spindle. The inside diameter of the bottom bracket shell is 41 mm. I did fine some information for a bottom bracket to accept a 30mm diameter spindle https://wheelsmfg.com/bottom-brackets/bb86-for-30mm/bb86-to-30mm-kit-for-pressfit-86-92-bottom-bracket-with-flanged-dual-row-black-oxide-sealed-bearings.html, however I still think this would be too small. Any suggestions. Thank you.

Found a solution. Luna cycle makes a 41 pressfit that works with the bbshd. I haven’t yet installed it, I ordered it, I’ll update the post when installed.
