Technologies:
- Shadow RD+: 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.
