It's not really that forward though. (seat is actually in the middle of the straight clamp)
The seat tube angle is slack and it's 76cm ( probably more like 80+ cm if you measure from the top of the saddle) from the BB. So if you draw a line from that point you can see that it's pretty far rearward without forward compensation.
My 180mm spindle is also a little more forward in the 3'oclock position also.
This set-up makes the most power yet for me (subjective feeling)
