Shimano SLX FC-M7120 Mountain Bike Crankset New 170mm

Shimano SLX FC-M7120 Crankset: Precision Engineering for Trail-Riding Dominance

Designed for riders seeking uncompromising performance on rugged trails and technical terrain, the Shimano SLX FC-M7120 crankset combines cutting-edge technology with minimalist efficiency to elevate your mountain biking experience. Engineered for modern 1x drivetrain systems, this crankset delivers unwavering stability and power transfer while maintaining an impressively lightweight profile—ideal for enduro racing, all-mountain adventures, or aggressive cross-country rides where every gram counts.

At its core lies Shimano’s Hollowtech II technology, a hallmark of precision engineering that optimizes stiffness-to-weight ratios for responsive pedaling under high torque loads. The hollow-forged aluminum crank arms minimize rotational mass without sacrificing strength, ensuring energy is channeled directly into forward momentum rather than wasted on flex. With a 55mm chainline and 178mm Q-factor, it strikes an optimal balance between efficient power delivery and ergonomic pedal positioning for all-day comfort during grueling descents or sustained climbs.

Boost hub compatibility (141/148mm) aligns seamlessly with modern trail bike geometries, while the Direct Mount chainring interface simplifies setup for riders upgrading to 12-speed systems—though chainrings must be purchased separately to customize your gear range. Built for versatility across disciplines from technical singletrack to aggressive trail riding, its black-anodized finish resists wear while maintaining a sleek aesthetic that matches any build kit.

Key Advantages Over Competitors:
– Hollowtech II Spindle: Superior strength-to-weight ratio vs. solid-spindle designs
– Boost Hub Readiness: Future-proofed for wide-trail wheel standards
– Direct Mount Integration: Streamlined setup compared to traditional bolt-on systems

Ideal for riders prioritizing lightweight performance without compromising durability, this crankset pairs perfectly with Shimano’s DEORE XT or SLX groupsets but requires a compatible bottom bracket (sold separately). Whether carving through loose rock gardens or charging through tight switchbacks, the FC-M7120 ensures every pedal stroke translates into confident traction and control—making it a standout choice for serious trail enthusiasts demanding precision engineering at an accessible price point.
