The Shimano Alivio FD-M3120-E Front Derailleur is a SIDE SWING, E-type mount front derailleur engineered for 2x9-speed MTB drivetrains. Utilizing Shimano’s SIDE SWING technology, it offers enhanced cable routing, lighter lever action, and smooth operation, while the E-type design improves clearance for large wheels and short chainstays, making it ideal for modern trail and rear-suspension bikes.

Compatible with front double chainrings (36-22T), the FD-M3120-E provides smooth, quiet shifting, powerful outward shifts, and a wider traction range to reduce chain rub. Its versatile design accommodates chainlines of 48.8 mm and 51.8 mm, and features angled stroke adjust screw, angled clamp band, and 4 link bushings for precision and durability.
