FSA K-Force Light BB386EVO BH Logo

Description

Resulting from a collaboration between BH and FSA requiring a BH Ultralight 747g Frame that uses the new BB386EVO bottom bracket standard to great effect, saving weight and increasing stiffness. Welcome to the LTD Edition BH - FSA K-Force Light BB386EVO crankset.

K-Force Light BB386 represents the latest evolution of the carbon cranksets. Updated with contemporary graphics emphasize the racing and winning heritage of the model line. K-Force Light arms are molded with a removable bladder process that allows maximum compression of the carbon material with the lowest possible void areas.

Current road BB shell width is 68mm.
BB30 and PFBB30 systems have a 30mm spindle diameter and set the bearings inside the frame with the outer edge remaining at 68mm, so the crankset spindle is designed around a 68mm system.
Standard systems use external bearing BB cups that push the edges to 86.5mm.
GXP, Shimano standard and FSA MegaExo, etc., basically have crankarms designed around a 24mm spindle diameter and an 86.5mm spindle length since they require the external BB bearing cups.
BB386EVO is designed with a 30mm OD spindle and an 86.5mm wide bottom bracket shell.
Therefore, BB386EVO uses the larger 30mm spindle (lighter, stiffer) of the BB30/PF30 and the 86.5mm bearing width (wider, stiffer), giving it all of the benefits of each system with none of the drawbacks.
