The Shimano Alivio FC-M4000 is a mountain bike front chainwheel crankset designed for 3x9-speed drivetrains. Here are its key features:
OCTALINK Interface: The FC-M4000 crankset uses Shimano's OCTALINK bottom bracket interface. This system provides a secure and reliable connection between the crank arms and the bottom bracket spindle, ensuring efficient power transfer and durability.
Chainrings: The crankset comes with three chainrings with tooth counts of 40-30-22T. This configuration provides a wide range of gear ratios suitable for various terrain types encountered during off-road riding. The combination of chainrings allows for smooth shifting and efficient pedaling across a range of speeds and inclines.
SHIMANO Logo: The crankset features the SHIMANO logo, indicating its authenticity as a Shimano product. Shimano is known for its high-quality bicycle components and innovative technology.
Chain Guard Options: The FC-M4000 crankset is available with or without a chain guard. The chain guard helps prevent the chain from derailing and protects the rider's clothing from grease and dirt. The option to choose between cranksets with or without a chain guard allows riders to customize their setup based on their preferences and riding style.
Overall, the Shimano Alivio FC-M4000 crankset offers reliable performance, a wide range of gearing options, and the flexibility to choose between chain guard configurations, making it suitable for various mountain biking adventures.
