Like I said earlier, this thread is more about the method for analyzing bike performance. The question of "why" is less of an issue. As stated earlier, I need more attempts on the Mondonico to have better data - it's only had one year and I'm still getting comfortable with this bike.
To your specific question, the Felt has been through different set of tires (23 and 25) and the Mondonico is running my standard 700x25 tires. My next project to upgrade the Mondonico will be a wheel set, the wheels that are on it are a mismatch of 20 year old rims.
