Familiarity: I've put it through the wringer
I run this with ultegra di2, rotor 50/34 oval chain rings, and a sram 11-36 road cassette. It works perfect in every way . But...
If you run enough chain to go big/big, it loses tension for the smallest 3 gears in the 34. Keeping tension on the b-screw helps this. The best way to run it would be with a 46 or 48 big chainring and shorten the chain. Even better, but I don't know if this is possible, would be to program the di2 so it doesn't shift to big/big.
I have a steep hill to my house that I lovingly call Ruinit hill, cause no matter how good your ride was, paperboying up this hill ruins it. Now with the 36t, not a problem. Glad to see this at Competitive.
