Shadow RD Technology*
*Shadow RD:ÌÎå«ÌÎ_Traditional derailleurs extend wider than the profile of your bike. With its low-profile design, Shadow RD is a more compact derailleur that fits closer to the frame, with more direct cable routing. Shadow RD maintains a consistent distance to the cassette for increased shift stability. The reduced body width creates a sleek and smooth appearance, ensuring less damage in a crash.
Di2:The power and precision of Di2 is unmatched. It enables beautifully smooth shifting both front and rear. The lack of maintenance and adjustment is impressive: once you‰Û¡ÌÝåÁÌÎÌÌ´åÈve customized your Di2 to shift to your preferences, it will continue to do so endlessly.
