K-Force Light 12-speed MTB Chain

What Our Gearhead® Experts Are Saying:

"I swapped to the K-Force Light MTB 12 Speed Chain for my trail bike, and it’s been a standout. The nickel outer and black inner plating look sharp, but more importantly, it runs incredibly quiet and smooth. Even after muddy rides and long climbs, it shifts cleanly and hasn’t shown any signs of stretch or rust. It’s a dependable chain that performs well under serious abuse."

From steep alpine climbs to rocky descents, the FSA K-Force Light MTB 12 Speed Chain delivers the consistent performance we count on for every ride. Built for modern 12-speed mountain drivetrains, it’s engineered to balance strength, precision, and lightweight design—keeping shifting crisp and quiet when conditions get rough.

FSA uses a nickel-plated outer link and black inner link combination to boost durability and corrosion resistance while giving the chain a sleek, trail-ready finish. With a narrow 5.25mm width and a low-friction design, it moves smoothly across cassettes and chainrings for fast, reliable engagement. Whether we’re pushing through wet roots or dry dust, this chain ensures every pedal stroke translates into forward momentum.
