This is a more specific article than Using 30mm spindle cranks with press-fit BB92 bottom brackets and is based on fitting Cannondale Hollowgram SISL cranks with a direct mount chainring to a Trance X 29er frame.
After a reasonable amount of trial and error I found that the following works well:
- BB92 x 30mm BB kit from RWS with Enduro press fit bearings;
- 125mm spindle (part number A3148)
- 1mm spacer each side;
- 0.5mm additional bearing shield either side;
- wavy washer on non-drive side.
