The seat tube angle on the RB's was steep compared to Riv's current offerings, at least in my frame sizes. My 56cm RB-2 has a 73 ST, whereas my 57cm Romulus has 72.
So by the butt-back theory you're advancing, my Romulus should be the more powerful bike. But it isn't; the RB-2 is. So this brings us back to Jim Thrill's post as expressing the likely combination of factors: "short chainstays, a steep seat tube, and probably low bars."
