Ultegra FC-08 chainset 11 speed, chainrings say 11 speed on them but this chainset looks identical to the 12 speed R8100 chainset so will likely work fine with 12 speed or 10 speed. New style cranks the same as the R8100 the chainrings also look identical. New still in box complete chainset with left and right cranks. This listing is for 52-36 chainrings with 172.5 crank length, photos may be different
