Shimano Deore M4100 2×10-Speed MTB Crankset – New FC-M4100-2

Shimano FC-M4100 Mountain Bike Crankset: Precision Engineered for Trail Dominance

For riders tackling steep climbs and technical descents alike, the Shimano FC-M4100 Crankset is built to deliver razor-sharp shifting performance under demanding conditions. Its sleek two-piece aluminum construction maximizes stiffness while shedding unnecessary weight—ideal for enduro racers or all-mountain enthusiasts chasing every second count on trails or podium finishes. By efficiently channeling power from your pedals to your drivetrain, this crankset ensures every ounce of effort translates into forward momentum without flexing under high torque demands.

Designed specifically for MTB setups using HG-X 10-speed chains, this crankset maintains flawless synchronization even when navigating loose terrain or rapid gear shifts during high-speed descents. Its asymmetric Shimano Asymmetric BCD configuration (96mm outer/64mm inner) optimizes chainline alignment for smoother engagement while reducing lateral stress on your drivetrain—a critical advantage when paired with modern wide-range cassettes. With compatibility tailored for both 135mm and 142mm MTB hubs, it seamlessly integrates into existing builds without requiring costly upgrades or adjustments.

Whether you’re conquering rocky singletracks or carving through tight switchbacks, the FC-M4100’s double chainring setup (36/26 teeth) offers a balanced gear range for tackling varied terrain effortlessly. The compact 9/16” spindle accommodates popular pedal systems without compromising stability at high speeds or under sudden braking forces—a must-have feature for aggressive riding styles.
