The new low-profile design of Shimano Shadow RD increases its shift stability and gives the rear derailleur a sleek and integrated appearance. Race endurance is guaranteed, through the optimized slant angle. The wide compatibility of two specific rear derailleurs (GS for cassettes 11-25T to 11-30T and SS 11-28T to 11-34T) will secure a smooth ride in even the highest and steepest mountain areas.
