That said, extrapolating from the pros, they ride a very broad range of setback...from 40mm to 115mm or so. Many factors at play. I move mine around a bit as it turns out....currently around mid pt of 25mm setback post with 73 deg sta. To me, riding behind this closes the hip angle too much for comfortable drop riding.
Not everybody needs to ride in the 'backseat' however and if the OP is light, fit and young and his pedal forces are high enough, then he might be OK with a straight post.
