I am wondering does anyone know the difference in the dedacciai tubes force 7003 (Cramerotti frame) vs. the SC 61.10A (Guru Chrono frame). I am wondering about strength, stiffness, and which will be a more durable tube set/frame. I hav e-mailed Dedacciai, Guru, and Cramerotti, but no one has gotten back to me. So I thought I would try here.
