Question: is it possible to pressfit a BB30 (or PF-30 as Spesh calles it) on a SJ HT Comp Carbon, instead of the GXP fitted on the stock model? It seems the SJ HT Expert Carbon is the exact same frame, which has the BB30.

Thats wrong. BB30 isnt equal to PF30. Speci has brought a compatibility list online. Have a look here:

S-worker, thanks. So I could change the GXP on the Comp for PF-30 press in cups for BB30 crankset, if I'm not mistaken?

 

[S-Worker]

Thats right. But why do you want to change the nice sram crank which comes with the bike?

 

[butterscotch]

Hmm, I think they are entry level cranks and no pressfit (Sram S1250?). I would like to change them to XO or XX cranks. With PF-30 that is.

 

[S-Worker]

I would dismount the cranks, weigh them and afterwards you can decide if its worth spending the money for a new crankset. Your crankset is a sram custom made set which isnt available normally. What i read about it is that its a high quality set. So a possibility is to put them on a scale.

So has anyone weighted the S1250 GXP that comes on the SP HT Stump Comp?

 

[keoman]

646 gr for a naked crank arms (no rings, bolts, bb, etc)
900gr complete with bb, rings, etc

as a reference an XTR m970 naked is 535gr

So, regarding compatibility, no mention of an Hollowgram crankset? In my opinion it is compatible but not sure, any thought?
