For future reference, non-descriptive subject lines like "Question" tend to trigger the "mess with the newb" response.
If you really have multiple records of riding the same route on the two different bikes; enough data that differences in weather, traffic, health, and quantum gravity effects all equal out, then you're left with the efficiency of the bike (weight, friction, aerodynamics) and the bike-rider interface (size and ergonomics).
