I know I've seen post on it earlier, but couldn't find it.

Whats your take, I'm debating between 3 bikes 2 with 700C, one with 26. I've ridden all 3, and didn't see much difference, except distance behind the seat and the center of the rear rack, which is 2 inches shorter on the 26. I know it is mostly geometry that explains it, but what other differences are there.
