Truvativ spec their own bearings which are non industry standard sizes
[devil’s advocate] I have some very much industry standard (actually, never looked anywhere other than BETD so not so sure about ‘standard’, but nevertheless affordable and available) enduro bearings pressed into my dead GXP cups and they are ace, well sealed, long lasting, and £20 a pop to replace if you can be bothered to press old ones out and new ones in. ….Or you can spend 2-3 times as much for a hope one.[/devil’s advocate]
Never looked at the sizes/numbers of my howitzer’s bearings, mind…
And yes, get slx or xt and you’ll be reet. Or even better and cheaper, try finding on classified/ebay some of the old hones on with the steel pedal insert (they have a bulge at the pedal thread which the normal ones don’t have, if the seller doesn’t know)
