Got the 50T & 34T ring for my Ultegra 6800. The 34T, inner chainring, works great.
Got the 50T & 34T ring for my Ultegra 6800. The shifting of 50t outer chainring was much slower and temperamental compared to the Shimano but works fine for my indoor setup. I wouldn't use this for as replacement of the outer ring for my outdoor setup but definitely will use it for the inner chainring. The mismatch aesthetics is another why I wouldn't use it.
