The EVO386 (also known as 386EVO) standard uses the widest bottom bracket shell at 86.5mm for maximum frame stiffness. Our EVO386 BB houses Grade 3 silicon nitride angular contact bearings with DLC-coated races inside precision-molded cups. The extra-wide bearing spacing delivers the best lateral stiffness of any BB standard — paired with ceramic bearings, you get both stiffness and efficiency. Compatible with 30mm spindle cranks from SRAM, FSA, and Rotor.
