The handlebar is beautiful without a doubt, but some things remain inexplicable for a handlebar in this price range, in my opinion.
With proper taping (up to the "step"), two open holes remain at the bottom of the handlebar (probably from semi-integrated cable routing). The problem is that there's no way to plug these enormous holes, and dirt, water (when washing the bike), and mud accumulate inside the handlebar. This can be a problem, especially for those like me who use the EW-RS910 Di2 control unit in one of the two handlebar caps: it creates stagnant water at the electrical connections.
I tried to report the issue but was simply told that the problem doesn't exist if the bike is washed properly (as if I were stupid, or as if mud doesn't get in even while pedaling).
In conclusion: it's nice, but for €1200, I expect a different product (and service).
