FSA SL K Light BB386EVO Crankset 4636T. Light, stiff, strong, and featuring a super versatile bottom bracket standard, the FSA SL K Light BB386EVO Crankset sets a remarkably high bar for road or cyclocross crank goodness. FSA uses state of the art manufacturing processes to construct hollow carbon fiber crank arms that are ridiculously stiff and seriously light the whole crankset weighs in at just 556g. There's more stiffness to be had courtesy of the BB386EVO 30mm spindle. It's constructed of 7050 aluminum to keep the gram count low and perhaps best of all the BB386EVO standard can be adapted to virtually any road or cyclocross frame. That means if you swap frames and find yourself with a different bottom bracket shell, you can simply adapt the bottom bracket rather than purchasing an entire new crankset. Just genius. This version of the SL K Light BB386EVO crankset features a compact 4636T chainring set up that delivers gear ratios perfect for cyclocross bikes as well as aficionados of gravel or adventure road bikes. The aluminum chainrings shift smoothly with their ramps and pins and they're hard wearing, too, so there's plenty of mileage in them. And with the crank arms topped off with a unidirectional UD carbon finish, these cranks look as good as they perform.
