Right. So, what I meant, when I said, "if you separate out other factors," was that we're talking about wheel size and only wheel size. What you mean, when you say "in this case," is that you're adding another factor back into the equation, namely a bike frame and how much clearance it has. This is, of course, relevant. But now we're talking about more than just the wheel size.
