After much research I couldn't find the exact bearing size for the Truvativ GXP system.
I know that the GXP system uses a shim on the left bearing inner race , but I assume that the bearings are interchangeable with Shimano XT/LX items (25x37x7 bearings or 6805).
Can anyone confirm this? I cannot easily find spare Truvativ BB cups or bearings so I hope my deductions are correct.
