The groupset offers two specific rear derailleurs: one for cassettes 11-25 and 11-30 and one for cassettes 11-28 and 11-34 securing a smooth ride in even the highest and steepest mountain areas. Due to the integrated Shadow RD Technology with its race-proven low profile design the derailleur is more compact and fits closer to the frame ensuring less damage in a crash.
