FSA K-Force Light Crank Set

FSA is to be credited with the invention (if we can call it that) of the compact crank. They also get credit for offering the first carbon fiber crank that was stiff enough to be ridden by racers. The combination of smaller chainrings and carbon fiber meant that cranks, which often weighed a full kilogram weigh less than 700g; some less than 600g. They were as stiff as many of the old-style aluminum cranks and the 50/34 chainring combination moved the chain down the cassette, no matter how strong a rider you were. [Source]
