Sundial - I find my current recumbent uncomfortable after about an hour of riding, plus it's a pain to transport, so I've been looking at diamond frames.

I think the aspect that has me spooked is the more upright riding position of the flat bar hybrids I've looked at, vs. the more forward position of the curved bar road bikes I've tried. Leaning farther means lest wind resistance, but for me at this size, it's very uncomfortable. I don't mean just the strain on by back, or upper body. In that position there isn't a lot of clearance between my thighs and my body, and my boobs are in the way despite the steel belted sports bra. OTOH, while the more upright position is more comfortable, I'm concerned that as I add more milage, the increased wind resistance, and single grip position will become the greater limiting factor.

Maybe I'm over-thinking all this, and I just need to get something to start with, that has a good fitting basic geometry, and adjust as I go.

Thanks again, everyone. I appreciate the warm welcome.
