I still don't get it, bikes like Factor, S-Works, Look 795 Blade SR, and many others are a waste of money for average cyclist, they are not comfortable, stiff, and super expensive. If you cycle over 70km it is like riding on the brick. Ostro uses ol carbon lay up technology, it has ist limitations, (eg adding additional material is impossible) and imperfections. Also, you have not tried TIME Alpe d'Hues 01. This is the best bike ever, if you like balance, stiffness, and control with exceptional technology. Using Japanese or American made steel bearing with higher smoothness give an identical effect and BB quality.
