Inserting a sleeve for a BB30 isn't a big issue for me. But a couple of mechanic-friends have told me was a PITA it is to remove a glued sleeve from an S-Works frame. Since an aftermarket S-works crankset has little resale value, I'd like to put it back on the bike if/when I flip it for another model. My gripe is mainly that I wished Spec would conform with the BB30, which is rapidly becoming industry standard. Same with their distinct bolt pattern that won't let me use different rings. Its like Pinarello and their weirdly sized seatposts... I keep thinking "why?"

(Keep in mind that I have the same non-conformity complaints about Internet browsers and clothing dress sizes)
