    Replace Crankset bearings - Hollowtech vs GXP

    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.
    thanks

    I found an old thread that calls for a 24x37x7 bearings for the GXP BB -
    But that size is not standard - and I think it's a typo

    Check here: http://www.enduroforkseals.com/id180.html

    Some of the best you can get. You can buy cups w/bearings or just the bearings. Also have ceramic.

    thanks for the advice, I'm interested in the bearings only, and Enduro bearing/seal kit is very reasonably priced.

    I still think that the the Sram and Shimano bearings are the same, however, but it seems that no one has the Sram bearing specs.
    thanks

    Enduro bearings are far superior to Shimano/SRAM/RaceFace. If you search for a thread by Hecubus, it shows in detail what it takes to change out your bearings with some nice pics.
