Why? Shimano spokesman David Lawrence said that the company isn't yet satisfied with the product, and feels that improvements in performance, weight and finish must be made before it can be branded Dura-Ace.
In fact, this entire system is still a work in progress – the hubs and calipers are XT mountain models, and the rotors are 160mm, to be reduced to 140mm in the full production versions. Shimano has entered other categories in similar fashion before. Its first compact crank was the R700 – not an Ultegra or a Dura-Ace. And its first hydraulic mountain bike brake was an XT – not the top-of-the-line XTR.
