Guys,
apologies if this has alreay been discussed. I've searched the forum, and couldn't find the answer I'm looking for. Hopefully this is a pretty straight forward one..
About to pick up a 2011 scott scale 30 which is running BB92 with an XT chainset. Want to swap for a SRAM XX which comes as either BB30 or GXP. Assume I need an adaptor, but which one?
There you go, short and sweet!
Thanks in advance 
You'll need to swap the pressfit BB cups for GXP versions, you can't adapt Shimano bearings to take GXP axles.
OK, so I have the choice of either the BB30 or GXP version then(?) recommendations?
No. only GXP will fit. BB30 (PF30) is a larger diameter cup that wont go in the Scott shell. Just use the Sram pressfit GXP cups.
fantabulous - thanks Blazin
No problemo.
word
I think those are for converting a hollowtech external BB to a GXP aren't they? The Scott Scale is a BB92.
I think the Hope adapters only fit the Hope BB?
Could be wrong.
Might be easier just to keep the XT or use XTR?
Hollowtech cranks fit BB92 in the same way as a external BB. You don't use different spacers or anything. So converting a BB92 to GXP should be the same as converting a external 24mm bb to GXP. Yes?
I guess you might have to trim the external seal or get a blue one.
I don't know if this works, but I think it should.
