Same/similar reach?
No, I just did a field change (flipping stem over) between CX races, and never properly accounted for reach. So the reach is shorter. But that was OK for me. I really noticed it on hairy descents where i could drop my butt behind the saddle and use a MTB-like position.
if I was doing high-speed gravel I’d probably go back closer to road. But this was for CX with a sadistic course designer. Savage pitches. Sand descents, etc.
