I have both CF and Ti bikes set up similarly for racing (a vanity, I never do it) with same groups and similarly light cockpits, wheels and tires. The Giant TCR Advanced CF weighs 13.9 lb while the Everti Falcon Ti weighs 14.2 lb. Yes, Ti frames will weigh more at similar stiffness. And yes, Ti frames cannot be fine tuned to the extent CF can, an extent which to me is overkill. But there is no way that modern Ti frames can be considered noodly. They are very stiff. Besides those two factors Ti is a marvelous frame material. Beautiful, comfortable, stiff yet resilient, and durable. I love both bikes, and don't believe an accomplished racer could turn in different results on the two bikes. There is no reason both Ti and CF bikes can't be your only bike. Also no reason either shouldn't be your second bike. After all is said and done, it is whatever you want. The performance differences are imaginary.
