386EVO Bottom Bracket

The 386EVO standard is similar to the PF30 standard, but using a wider shell (86.5mm). The bearings (6806) are pressed in to composite or aluminum cups that are then pressed in to the frame’s bottom bracket. While originally designed to work with 386EVO cranks that have a 30mm spindle, many cranks with 24mm or 24/22mm spindle diameters can be used with 386EVO frames when using our adapters.
