Product Review: FSA K-Force Light BB386 EVO Crankset

K-Force Light BB386EVO Crankset

When I first opened the box for the FSA K-Force Light BB386EVO Crankset to build up my new 2020 Bottecchia Emme 4 team bike, my first thought was it looked like it came off a spaceship.  The design is very futuristic looking and it felt crazy light. The lines give it a very futuristic Sci-Fi feel and the black and grey color scheme and unidirectional carbon layup match almost any bike and components. I was also amazed by the weight, which comes in at only 534 grams.

In the past, I have had trouble with cranks that were light and ended up flexing too much under a high load, but these cranks were very stiff even while sprinting and standing out of the saddle and putting the power down.

Shifting between the chainrings from the large chainring to the small chainring and vise versa was also smooth and easy due to the efficiency of the chainring design and the ramp design along with the splines on the chainrings to allow for some extra stiffness when shifting which allow for extra crisp and reliable shifting with the front derailleur. The FSA K-Force Light BB386EVO Crankset also incorporates a self crank extractor for easy installation and removal of the cranks.

The BB386 alloy spindle also means that the crank will fit in a wide variety of frames with different bottom bracket standards as FSA makes different spacer /adapters options for most of the current bottom bracket standards. The FSA K-Force Light BB386EVO Crankset has to be one of my favorite cranksets and it certainly turns heads on rides due to the cool beefy and clean futuristic design. 

Key Features Include:

  • A very clean color scheme and futuristic design
  • Extremely lightweight,
  • Very stiff
  • Compatible with most bottom bracket systems on the market for added versatility.

If you’re looking to build your bike from the ground up or upgrade your current crankset, the FSA K-Force Light BB386EVO Crankset is a nice upgrade that could help your power transfer and lighten up your bike. The crank arms are carbon that is a unidirectional hollow carbon crank arms and machined chainrings to offer an extremely light and efficient crankset.

The Team used the FSA K-Force Light BB386EVO Crankset with 53 x 39 chainrings and I used a 175 mm length crank arms at the time of the review. However, the crankset comes in different chainring configurations and crank arm lengths to fit your needs. This Crankset is also included with the FSA WE Groupset.
