Thank you for your tips and offers. Let me took out the spindle and have a closer look inside since I need to replace the bearings. I will get back to you. Any rough idea how much will those custom made spindle cost?
I see. I guess mine 92 and yours 93 have different BB shell. Mine is press fit type with 78mm shell width. Fitted with 113mm spindle but just too narrow to fit a Cook Bros RSR. I definitely need a longer spindle just don't know how long.
