BB386 EVO is a road bike bottom bracket standard introduced back in 2011. The BB standard is based on a frame shell width of 86.5mm and inner diameter is 46mm.
The inspiration behind the design was to oversize. While similar to conventional threaded, BB90/95, and PF86/92 bottom brackets, BB386 EVO incorporates a larger 30mm diameter spindle.
Why do you care? Well, that oversized spindle and shell increases stiffness right where it’s needed most. Ever watched a BB shell twist side-to-side when hammering on a trainer? Yikes!
A mountain bike version 392EVO exists, but sightings are more rare than the Loch Ness Monster.
Bottom brackets are the same between both mountain bike and road versions.
