Overview
Chainring Shimano Alivio FC-M4000 30T 3x9
Shimano Alivio FC-M4000 30T is a genuine replacement middle chainring designed for Shimano Alivio 3x9-speed mountain bike cranksets. The 30-tooth chainring is intended for a 40-30-22T triple chainring combination, providing versatile gearing for flat roads, climbs and mixed off-road terrain.
Manufactured from durable steel, the chainring offers excellent wear resistance and long-lasting performance. Shimano's optimised design helps maintain smooth chain movement between the front chainrings, ensuring precise and reliable shifting even in demanding riding conditions.
Featuring a 96 mm bolt circle diameter (BCD) and four mounting holes, this chainring is compatible with Shimano Alivio FC-M4000 and FC-M4050 series cranksets, including the FC-M4050-B2. It is an ideal replacement for a worn or damaged middle chainring, allowing riders to restore drivetrain performance without replacing the entire crankset.
