Most people buying a new bike for the first time in 10+ years ride faster but that's due to feeling good about the new purchase and wanting to justify the cost. So you ride harder and longer because it looks and feels better. Compared to a CAD 3, a newer CF bike will feel more comfortable and may actually help you recover more after really hard rides. CAD 3's are known for the stiffness, which is great for sprinting but can be a little rough after a while. The wheels will be a little faster as well, especially if you go with aero ones.
