MTB Derailleurs

Mountain bike (MTB) rear derailleurs are crafted to ensure precise shifting performance, even on muddy or debris heavy terrain. Modern designs reduce the gear's protrusion on mountain bikes decreasing the risk of damage. Find an MTB derailleur compatible with your drivetrain at Sigma Sports.
