Reviews over the

FSA Dura Ace 9000 / Ultegra 6800 / 105 5800

These rings fit well in a 6800 chainset. They seem very good quality and shift well, although not as well as the Shimano originals. FSA do sell some profiled bolts so that the chainset blends in with the flat chainrings and you use the torx bolt from the old rings. However, they will fit with standard chainring fixings (you need the nut and bolt type instead of the Shimano torx bolt). The chainring seem stiff enough compared the the old ones.
