Yes, we have the Ti couplers and they have the Aluminum models but the frames use the same diameter tubing all around. Ignoring customer-specific options and the associated accountraments, the only other cosmetic differences that were obvious to me was the grain of the main tubes (visible only under the translucent blue coloring as the orange was opaque), some different methods associated with how cables stops are incorporated and the appearance of 'blisters' around the cable stops, guides and entry/exit points on the frame that are not in evidence on older models like ours. You can see them somewhat on
uspspro's white Calfee where the cable openings exit from the headtube along the downtube, at the brake cable stops and where the brake cable passes through the frame joint at the captain's seat tube and top tube.
As for frame stiffness, the only thing that any of us have observed is that our frames do not exhibit any notable deflection in any plane and are just downright plush compared to our previous steel-framed mounts.
