Been speaking to BMC about it. its effectivley got a couple of corners cut because of cost (cheaper layup etc), but i wouldn't let that worry you.
the seatpost is not a team machine one but the one from the granfondo, or very similar so its very comfy. total weight for the framesets are 1380 for the SLR01 and 1530 for the SLR02. i've been assured you will get excellent stiffness to weight ( better than all of the preceding models ( RM/SL/ and last years SLR01)) from the SLR02.
in terms of bang for buck in the uk you can get a 105 equipped one for £1800. take the OE wheels off (and replace) and you've got an excellent bike.
I'm probably going to get one for the classics! or if i save for a couple of months i'll just get an ultegra equipped SLR01
