Natalie can give me the same fit/body position on the bike, regardless of the size of the wheels. That does require some small changes in the frame geometry, but the most crucial thing is that the FIT will be the same.
So my height, body size, etc. are not really germaine to the conversation I want to have in this thread.
What I'm looking for feedback on is your thoughts on the pros and cons of the wheelsize. Those of you with 650s, am I unreasonably concerned about tire/tube availability? etc. Aesthetics matter to me too.
EDIT: I just tried to post links to images of the proposed design, but there are access issues, so it won't work.
The 700c bike has 12 degree slope in the top tube of the 700c, which I'm not sure I care for. And the small frame looks scrunched between those big wheels. The 650c bike looks proportionate to me.
