Think of the bottom bracket as a fixed reference point. On the Cervelo, with its less steep seat tube, the top of the seat tube will be further back relative to that BB. At the same rider to pedal position, this means that the top tube has to reach further under the seat. And then, because the top tubes are nearly the same length, this means that the head tube is closer to the rider.
