that sounds like a nice deal but ideally i'd like a 50/34 and 170mm with a gxp bb. specialized arms will need bb30 right?

edit: did a little bit of reading and found out that they will be compatible with bb30/pf30/osbb. my frame has a pf30 which has an adapter for gxp (i believe) and I use gxp cranks. i would like to try native bb30 stuff some day but i'm just (possibly irrationally) scared of screwing up 1) the pf30-gxp adapter uninstallation and 2) the bb30 installation and dealing with a creaking bb.

For my next frame (still deciding, lots of looking) i'll maybe get a native bb30 crankset. let's see.
