Replacing bearings in original SRAM GXP bottom bracket
Is it pressfit or BSA? if pressfit then no, you’ll knock the cups out and damage them, if its BSA then you probably can, but its hardly worth it as the bearings cost more than the BB.Posted 7 months ago
SRAM gxp bbs are terrible in my experience, always fail on one side quickly.
You could replace with a Hope with a GXP conversion kit which will allow you to change bearings easily in the future.
Alternatively, take the new BB apart and fully clean out the stock grease and re-fill it with decent waterproof grease from new. then maintain it every few months.
Is this possible?
I’ve repacked the BB with grease but it is still creaking so I’ve concluded that the bearings are shot and need replacing. A little bit of digging on the internet has told me that the size I need is MR2437-2RS for my threaded external bearing BB, IE not press fit or bb30. But what I can’t find out is if this is only for ones like the Hope or Uberbike ones which are designed to be replacable. Any one know?Posted 7 months agowelshfarmerSubscriber

You can put new bearings in the old cups (24mm x 37mm x 7mm)
You dont need the fancy tools, or even take the old cups out of the frame, just knock the old bearings out of the cups.The reducer/ adapter shim that you already have in the GXP BB can be reused, have a look at steps 8,9,10 etc .
New bearings may need glue to hold them in the cups. Truvativ / GXP BB cups are not the best.
Enduro bearings are about average quality, but the seals in the kit are possibly a help.
Anything is better than GXP truvativ bearings.Posted 7 months ago
