I couldn't get the PDFs to open.

Personally, I prefer the 700c wheels. But, then again, I ride a ~49cm frame. If I were smaller and needed a smaller bike, I might feel differently about it.

For me, standover height is never an issue, so I don't have that concern that might warrant smaller wheels. I guess I've been lucky- small frames with reasonably "traditional" geometry work well for me. I haven't experienced any toe overlap issues on my roadie, though my commuter/cross frame is another story. It's something that I've grown accustomed to on that bike, and hardly notice anymore.

I prefer the 700c wheels b/c they allow me and DH to swap wheels (which happens frequently in our house). I had a hard time finding 650c tires that weren't race tires when I owned a bike with those size wheels, and they were almost always an internet or special order purchase. Tubes were fairly easy to find. For me, easy access to standardized parts is important.

As for the acceleration difference, it's not something that I remember loving about the 650c bike, or hating about my current 700c ones. It just is.

*shrugs* I dunno. It seems like a personal preference thing, and my preference may very well change as I log more miles. But, for now, 700cs work for me.
