Interesting note. Actually it seems like the styling elements extend to the levers only as decals, the flat bars look like standard MTB units and the brifters are dominated by the ergonomic concept. But the calipers are really differently styled than the ones in the road bike line. The R405, 505, 805 (Tiagra, 105, Ultegra) all look about the same with a sort of teardrop shape around the piston but the Metrea has styling that goes with the RD.

I still haven't found any of this stuff for sale except on bike24, but I don't know websites on the continent, perhaps someone else does.
