However, I hit occasionally shoe against the front tyre so when measuring frame I would also pay attention to bottom-bracket centre - front-wheel centre. In smaller bike it is 2,5cm shorter (both bikes crank 170mm).
yeah... don't decide your framesize based on toe overlap. Unless you're making tight turns at low speed, it really shouldn't be a problem.
